Di-Chromatic InGaN Based Color Tuneable Monolithic LED with High Color Rendering Index

Applied Sciences, 2018
We demonstrate a phosphor free, dichromatic GaN-based monolithic white LED with vertically stacked green and blue emitting multiple quantum wells. The optimal thickness of GaN barrier layer between green and blue quantum wells used is 8 nm.

Vertical Cavity With a Chirped Heterostructure Dual-Period High-Contrast Grating

IEEE Photonics Journal, 2022
A vertical cavity using a chirped heterostructure dual-period high-contrast grating (HCG) by simple fabrication is demonstrated. The reflectivity spectra of the vertical cavity were measured, consistent well with the calculated results.

Observation of moiré excitons in WSe2/WS2 heterostructure superlattices [PDF]

Nature, 2018
Moiré superlattices enable the generation of new quantum phenomena in two-dimensional heterostructures, in which the interactions between the atomically thin layers qualitatively change the electronic band structure of the superlattice. For example, mini-
