Technical Terms Quantum Confinement: The effect observed when the dimensions of a semiconductor are reduced to the order of the exciton Bohr radius, resulting in discrete energy levels.

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 ...

In our case, the size of ZnS nanoparticles were found to be in the range of 2-4 nm which is same as the exciton Bohr radius (2.1nm) for a cubic ZnS structure. Hence the slight change of band gap may ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Achieving deterministic control over the properties of low-dimensional materials with nanoscale precision is a long-sought goal. Mastering this capability has a transformative effect on the design of ...

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 ...

Spiroindicumides A (1) and B (2), novel spirolactone polyketides, were isolated from a filamentous fungus, Chaetomium indicum, cultivated in the presence of a histone deacetylase inhibitor. Their ...

After many years, this classic two-volume treatise is now available again in an unabridged reprint. These volumes present the basic features of nuclear structure in terms of an integration of ...
