Coherent Control of Acoustic Phonons in hybrid Metal-Semiconductor System
Meg Mahat, Sergio Periera, Ian M. Watson +2
We demonstrate the modification of coherent zone-folded longitudinal acoustic phonons (ZFLAPs) oscillations in InGaN/GaN multiple quantum wells by the inclusion of metal nanopartic…

Spontaneous Emission and Ultrafast Carrier Relaxation in InGaN Quantum Well with Metal Nanoparticles
Meg Mahat, Arup Neogi
Subpicosecond wavelength non-degenerate differential transmission (DT) was used to observe the carrier relaxation mechanism in GaN based quantum well (QW) with and without metal na…

Observation of Coherent Folded Acoustic Phonons Propagating in a Hybrid Au- InGaN/GaN Quantum Wells
Meg Mahat, Tae Y. Choi, Arup Neogi
The coherent folded longitudinal acoustic phonons (FLAPs) in gold nanoparticles (NPs) imbedded InGaN/GaN sample have been studied using degenerate pump-probe technique. When the FL…
