We demonstrate electromagnetically-induced anomalous quantum dynamics of an exciton in a photonic band gap quantum well heterostructure. The exciton can be captured in k -space by emission and ...

The optical properties of few-layer (FL) GaSe are investigated using thickness- and temperature-dependent Raman scattering and photoluminescence (PL) spectroscopies. The vibrational modes exhibit ...

Stacking two dimensional tunneling heterostructures has always been an important strategy to improve the optoelectronic device performance. However, there are still many disputes about the blocking ...

Ulna and Radius Fractures: What You Need to Know The forearm is made up of two bones, the ulna and the radius. A forearm fracture can occur in one or both of the forearm bones. Some of the causes ...

The size of NCs of ZnSe was estimated to 1.98 nm, compared to the exciton Bohr radius of bulk material. We established a strong quantum confinement state for the NCS ZnSe. Using Nd:YAG laser at 1064 ...
