Our interdisciplinary research group is generally interested in materials relevant for devices like solar cells, LEDs, sensors, detectors, and transistors and the methods of fabricating such devices that are inherently low cost, on a variety of substrates.
While we are primarily an experimental group, we also do a small
amount of work on developing theoretical and numerical
methods for understanding the behavior of these materials and
devices at multiple length scales. Further, we are primarily an
engineering group, which means that all the interesting science
that you do in the lab should result in a workable and useful
device, or process, as a part of your research. Less commonly, we
are also interested in some important questions in
the science of disordered materials at nanoscale.
We are located on the campus of Indian Institute of Technology
Map), which is located in the Hauz Khas area of south New
We accept applicants with backgrounds in chemistry, materials science, electrical engineering, physics, and perhaps even mathematics, and allied areas. The precise title of your degree is not very relevant to the group, but your intellectual preparation, and passion for research is. If you have a background in, and are interested in surface physics and chemistry, condensed matter physics, low dimensional systems, device processing, light-matter interactions, material chemistry, thin-film growth, self-assembly of nanoscale materials, chemical synthesis, material and device characterization, devising new material and device measurements, instrumentation, etc., this group may be a good choice for you.
Regardless of your background, you need to be a careful and safety-conscious, methodical, ethical, intellectually curious, academically serious, hard working, patient, and self-motivated person by nature, possessing good communication skills, and capable of working effectively in collaboration with your colleagues, to be a good personality fit for the group.
If you are interested in joining us, you must satisfy the grad level admission
requirements of the Department of Electrical Engineering
(IEC group) or the VDTT
program. Admission to Electrical Engineering is quite competitive,
and the Departmental requirements for admission tend to be more
stringent than any Institute requirements. Candidates may apply,
depending on their qualification and specific situation, to the MS
or Ph. D. program. Admission to the MS
program generally requires a GATE score in either of
EC/PH/IN/MA/EE. The Ph. D.
program does not have this requirement, though your
application must persuasively demonstrate a defensible link to the
research areas of the lab, as well as the Department.
For the purposes of admission to Ph. D., the five years of study
involved in earning an M. Sc. degree are considered equivalent to
a four year B. Tech or B. E. degree. Students with a three year B.
Sc. degree are not eligible for admission to the Ph. D. program
according to the academic rules. Regrettably, the academic rules
do not currently permit admission of B. Sc. students into the MS
program without the GATE discipline requirement above, and
completion of minimum 4 years of coursework after 12th
grade. The number of years of study preceding admission to the Ph.
D. program determine the number of credits a student needs to earn
prior to the comprehensive examination, which formally admits a
candidate into the Ph. D. program phase involving full-time
research. For 4 years of prior study (such as for entry with B.
Tech or M. Sc.), this number is 24, while it is 12 for 6 years of
prior study (such as for B. Tech + MS).
Students with M. Sc. degrees in allied science areas (such as Chemistry and Physics) listed above are encouraged to apply to the Ph. D. program directly as long as they agree to undertake some coursework in EE to satisfy the transition requirements. Depending on the goodness of fit of their preparation in their B. Sc. and M. Sc. degree coursework, they are likely to be well-suited for interdisciplinary research in our group.
Undergraduate preparation for research in our group requires a
rich and extensive background in the areas mentioned above.
Several undergraduate programs in EE/ECE do not regularly contain
the relevant coursework, in some cases, lacking even a single
dedicated course on semiconductor devices. This would be to your
disadvantage during the application process for a research degree.
In such a circumstance, the coursework oriented M. Tech
(equivalent to an MS by coursework degree) programs at IIT Delhi
or in VDTT)
may be a better bet for you, especially in the Micro and Nano
Devices stream. If the content of your IIT Delhi M. Tech
preparation (as evidenced by the choice of electives) is a good
fit for research in FMDL, you could be well placed to apply
subsequently for an MS or Ph. D. admission. While this route may
delay onset of full-time research work, it would better prepare
you for it.
There is also the possibility of conversion of the student's
initial program (M. Tech or MS) into MS or Ph. D., provided the
student completes a certain number of credit hours, and maintains
a certain minimum CGPA. Details regarding this are decided by the
Departmental Research Committee, and the Dean's office.
Finally, both full-time and part-time routes to a grad school
degree exist at IIT Delhi. Since we are primarily an experimental
group, continuation after end of coursework in a part-time Ph. D.
degree, or a part-time MS degree is likely to be logistically
complicated for most applicants, and is not encouraged.
Prior research experience in a relevant area is strongly
preferred, as are students who hold valid national level
fellowships, such as CSIR or UGC.
Applicants who need financial support must note that vacant
positions either on Institute fellowships, or fellowships funded
by Department of Electronics and Information Technology, or one of
my projects, must exist for me to accept them in my group,
regardless of the criteria above.
If you interested in joining the group as a postdoc, please apply
Institute position, an SERB-funded postdoctoral
position, a DST-funded
KIRAN fellowship, a DBT-funded
Bio-CARe grant, or one of the many UGC opportunities,
etc., and send me an application below (after applying for, or
receiving one of these or other grants).
Please note that KIRAN and Bio-CARe opportunities are available
only for female candidates.
Students interested in an internship should consult a) GIPEDI program, b) SURA program, or c) DISA program before sending in an application.
If you are an undergraduate student at IIT Delhi (any Department)
interested in doing your B. Tech project with me, and are a decent
fit to the above, you are welcome to contact me by the month of
May at the end of your junior (3rd) year. You may need
to work in the summer to get started.
If you are an undergraduate student at IIT Delhi interested in a
mini project, or a self-study course, please understand clearly
that your grade in such a course will depend on serious hard work,
where you will be judged on the progress made. Students with other
motivations are encouraged to seek alternative opportunities.
Rarely, depending on our funded project needs, I may hire
temporary (1-3 month) project workers at grad level or above
(generally through advertisement). Any appointments to these kind
of temporary positions come with no implications for any degree,
or admission to the Department (or housing on campus). However,
the expectation for grad level applicants here is that in case of
a good fit, you should be able to qualify for grad level
admissions described above.
Please understand that student applicants who have completed
their undergraduate education (B. Tech, BE, BS, etc.) or certain
graduate degrees (M. Sc.) are expected to join the group for an MS
(preferable) or a Ph. D. (in some cases). If you are merely
looking for a temporary position (2-6 months) to buttress your CV
before you go into industry or grad school elsewhere, your
application for a project position would be generally unwelcome
unless I have advertised for temporary position explicitly.
