Dielectric Relaxation in Glassy Se100 - x Sbx
Chalcogenide glasses Dielectric relaxation
font style='font-size:12px;'>
2010/4/12
Frequency and temperature dependence of dielectric constant \varepsilon' and dielectric loss \varepsilon'' are studied in glassy Se1-x Sbx (x = 0, 0.02, 0.04, 0.06, 0.08 and 0.10) in the frequency ran...
Modeling Relaxation Length and Half-Thickness of Wood by Method of Gamma Radiation
Relaxation Length Half-Thickness Value Gamma Radiation
font style='font-size:12px;'>
2010/4/12
Relaxation lengths and half-thickness values of different types of wood were determined using gamma radiation from 60C0 source. Results show that oxystigma (Oxystima spp) has the highest relaxation le...

We review our recent results concerning the well-width dependence of the acoustic-phonon-assisted energy relaxation of two-dimensional (2D) warm electrons in modulation-doped GaAs/Ga1-xAlxAs multiple ...
87Rb NMR Relaxation and Vortex Dynamics in Rb3C60
87Rb NMR superconducting Vortex Dynamics
font style='font-size:12px;'>
2010/4/15
87Rb NMR relaxation measurements in superconducting fullerene Rb3C60 for various values of the external field are reported. In the normal state the results are in agreement with T1T= Constant. Below T...
