Ultrafast relaxation of hot phonons in Graphene-hBN Heterostructures
Dheeraj Golla, Alexandra Brasington, Brian J. LeRoy +1
Fast carrier cooling is important for high power graphene based devices. Strongly Coupled Optical Phonons (SCOPs) play a major role in the relaxation of photoexcited carriers in gr…
Optical characterization of electron-phonon interactions at the saddle point in graphene
Adam T. Roberts, Rolf Binder, Nai H. Kwong +5
The role of electron-phonon interactions is experimentally and theoretically investigated near the saddle point absorption peak of graphene. The differential optical transmission s…
Optical thickness determination of hexagonal Boron Nitride flakes
Dheeraj Golla, Kanokporn Chattrakun, Kenji Watanabe +3
Optical reflectivity contrast provides a simple, fast and noninvasive method for characterization of few monolayer samples of two-dimensional materials. Here we apply this techniqu…
Goos-Hanchen shift for higher order Hermite-Gaussian beams
Dheeraj Golla, Subhasish Dutta Gupta
We study the reflection of a Hermite-Gaussian beam at an interface between two dielectric media. We show that unlike Laguerre-Gaussian beams, Hermite-Gaussian beams undergo no sign…
Competition between structural and intrinsic dispersion in delay through a left handed medium
Dheeraj Golla, Subimal Deb, S Dutta Gupta
We study resonant tunneling through a layered medium with a negative index medium (NIM) slab as a constituent layer. We demonstrate large delays in transmission mediated by the sur…
