Influences of excitation-dependent bandstructure changes on InGaN light-emitting diode efficiency
excitation-dependent bandstructure InGaN light-emitting diode efficiency Mesoscale and Nanoscale Physics
2011/8/2
Abstract: Bandstructure properties in wurtzite quantum wells can change appreciably with changing carrier density because of screening of quantum-confined Stark effect. An approach for incorporating t...

IR Bismuth active centers excitation-emission spectroscopy
2011/9/2
Впервые получены 3-мерные спектры люминесценции (интенсивность люминесценции в зависимости от длин волн возбуждения и эмиссии) легированных висмутом волоконных световодов различного состава в широком ...
Carrier-Envelope Phase Effects in Multi-Photon Excitation
Carrier-Envelope Phase Effects Multi-Photon Excitation
2010/11/9
We present an experimental and theoretical study of multi-cycle pulse coherent control by carrier-envelope phase(CEP) under bichromatic radio-frequency(RF) field excitation. Using intense ultra-short...
Nuclear Collective Excitation by a Short Strong Laser Pulse
Nuclear Collective Short Strong Laser Pulse
2010/10/27
We derive the conditions on the average laser energy and the mean photon number such that
a strong short laser pulse causes collective nuclear excitation. We use the nuclear Giant Dipole Resonance as...
Transient energy excitation in shortcuts to adiabaticity for the time dependent harmonic oscillator
Transient energy shortcuts adiabaticity time dependent harmonic oscillator
2010/10/21
There is recently a surge of interest to cut down the time it takes to change the state of a quantum system adiabatically. We study for the time-dependent harmonic oscillator the transient energy exci...

The Electron-Photon Coincidence Method and its Application to Excitation of the 2P State of Atomic Hydrogen
Angular Correlation Electron-Photon Coincidence Excitation Electron Scattering
2010/4/13
Early measurements of atomic excitation by electron scattering observed either the scattered electron or decay photon. An excited state can not be completely defined by such experiments due to loss of...
