Effects of variable anisotropic-strain on the emission of neutral excitons confined in epitaxial quantum dots
Effects of variable anisotropic-strain neutral excitons epitaxial quantum dots
2010/11/22
We study the e ect of elastic anisotropic biaxial strain on the light emitted by neutral excitons confined in di erent kinds of semiconductor quantum dots (QDs). We find that the light polarization ro...
Slow highly charged ion O4+ induced electron emission from clean solid surfaces
Slow highly charged ion (SHCI) electron emission electron stopping power
2009/8/14
The total electron emission yields following the interaction of slow highly charged ions (SHCI) O4+ with different material surfaces (W, Au, Si and SiO2) have been measured. It is found that the elect...
Electron Cyclotron Emission Simulation from TCABR Plasmas
Electron Cyclotron Emission TCABR Plasmas
2010/10/27
Electron cyclotron emission due to electrons described by a particular distribution function has been studied. The latter presents an extended tail generated by the interaction of the Lower Hybrid wav...
Single Mode Optical Radiation Distribution and Reflectivity Calculations in Novel-Hot Electron Light Emission and Lasing In Semiconductor Heterostructures VCSELs
Optical Radiation Distribution Electron Light Emission Reflectivity Calculations
2010/4/12
In this work, we calculate the power reflectivity in vertical cavity surface emitting lasers (VCSELs) using a new method. In VCSELs, the stop band of the reflectivity spectrum should exhibit a dip at ...
Electron Field Emission Measurements from Boron-Doped CVD Diamond on Tantalum
Electron Field Boron-Doped CVD Diamond Tantalum
2010/10/27
Boron-doped polycrystaline diamond films grown by hot-filament-assisted chemical vapor deposition were studied with ultraviolet photoemission spectroscopy (UPS), Raman spectroscopy, X-ray diffractomet...
