Research Description

I am currently working on Coherent nature of phonons in semiconductors, essential for understanding the dissipation mechanisms, electron-phonon interaction , mapping of nanostructures and symmetry breaking effects in semiconductors.This research combines the optical spectroscopy techniques and quantum/semiclassical simulation strategies to comprehend the governing physical processes. 

Where in the world has your career been largely based until now?

India, Indian Institute of Technology Bombay (IIT-B). I am currently a DAAD bi-doctorate student at TU Berlin and Paul Drude Institute (PDI) for Solid State Electronics.

Why Berlin?

Berlin has a world class reputation in research in quantum technologies. Particularly, the importance given to fundamental science is far beyond any other nation. I believe fundamental research drives the applications of the future. Moreover, I wanted to experience the diverse and historically rich culture of Germany, particularly Berlin, where so many historical events have taken place. Lot of development of quantum mechanics took place here, including birthplace of many renowned physicists.

What fascinates you about your research area?

The simplistic way that I could tell anyone that I work on light to sound conversion (photoacoustics) and yet it feels fascinating. Research community is still evolving in understanding this phenomenon from quantum perspective. So I just know a drop from the ocean and that keeps me going.

How will your research change the world?

We will have better understanding of the heat and phonon transport  in semiconducting nanostructures and symmetry breaking effects, that will help us understand the behaviour of electrons and quasiparticles inside such systems, manifesting in developing efficient optoelectronic and electronic devices.

What major short-term goal are you currently working towards with your research?

As I am new to this field, so I am still evolving and trying to perform more experiments and gathering new data. Currently, I’m studying the phonons in superlattice structures (repetitive layers of different materials) and their interaction with the interfaces for evaluation of heat transport parameters.

How did you become interested in your specific topic?

I was working on a defence project with some specific predetermined goals. However I soon realised that research has to be performed on knowing the unknown and creating new knowledge. I used my project experience to start my own work on solid state devices and it surely propelled me in the right direction.

What is your preferred way to communicate your research to the broader public or other specific sectors beyond academia? Where can we see, hear or read you next?

Preferably conferences and peer reviewed purpose-led publications. But I have also taught a few courses on NPTEL portal and you can find it on youtube as well. I like to graphically depict my research to the audience.

Is there anyone else in the Berlin-Brandenburg area that you would love to collaborate with?

Berlin Quantum Alliance.

How does the academic culture in Berlin differ from the academic culture you are used to?

People are more open to discussions here and confident about what they are doing.

Has Berlin had any surprises in store for you?

Yes, it is a good place to study and live. I like trekking and going out, so I could find some cool places around. I’m from the Kashmir valley, located in the north most region of India, and I’m used to sub-zero temperatures. So I pretty much like the weather here. Expecting colder weather ahead.

What would your advice be for colleagues at home interested in a research stay in Berlin?

I will let them figure it out. But I would suggest them to look for an accommodation as early as possible.
