Condensed Matter Physics and Materials Science

In condensed-matter physics and materials science, semiconductors are the basis of several important nanotechnologies including electronics, optoelectronics, sensing, computing, and communications. 

In this regard, I'm working on tuning two-dimensional (2D) nanomaterial's structural, electronic, and quantum electron transport properties which have facilitated the new research paradigm in nano-electronic device applications.

I address several open questions:

(i) Can we tune the structural and electronic properties like bandgap of low-dimensional materials under extreme conditions (by mechanical strain, electric field, pressure, and temperature)?

(ii) Is chemical doping useful?

(iii) Are the tuned low-dimensional materials behave like direction-dependent anisotropic?

(iv) Are the tuned low-dimensional materials behave like diodes?

(V) Can we find the physics behind it?
