Analysis of optical gain and threshold current density of wurtzite InGaN/GaN/AlGaN quantum well lasers
The valence subband structures, density-of-states, and optical gain of (0001) wurtzite InxGa12xN/GaN quantum wells (QWs) are studied using a numerical approach. We used the effective-mass parameters of GaN and InN derived ...
A high-capacity scintillation proximity assay for the discovery and evaluation of ZAP-70 tandem SH2 domain antagonists
A scintillation proximity assay (SPA) is described, which quantitates the ability of compounds to inhibit the binding interaction of a select phosphopeptide with the tandem SH2 domains of the ZAP-70 protein tyrosine kinase. ...
Temperature dependence of excitonic energy in isolated Se chains formed in the channels of AlPO4-5 crystals
Optical absorption spectra of Se chains formed in channels of AlPO4-5 (AFI) crystals are measured in the temperature range from 80 to 298 K. The excitonic energy of the isolated Se chains is observed to shift to lower ...
