Electron mobility in dense argon gas at several temperatures

Electron Mobility Maximum in Dense Argon Gas at Low Temperature

We report measurements of excess electron mobility in dense Argon gas at the two temperatures T = 152.15 and 162.30 K, fairly close to the critical one (Tc = 150.7 K), as a function of the gas density N up to 14 atoms·nm−3 (Nc = 8.08 atoms·nm−3). For the first time a maximum of the zero-field density-normalized mobility μ0N has been observed at the same density where it was detected in liquid A...

Uniform electron gas at finite temperatures

We calculate the free energy of the quantum uniform electron gas for temperatures from near 0 to 100 times the Fermi energy, approaching the classical limit. An extension of the Vashista-Singwi theory to finite temperatures and a self-consistent compressibility sum rule is presented. Comparisons are made to other local-field correction methods, as well as recent quantum Monte Carlo simulation a...

Limitation of Electron Mobility in Modulation-Doped In0.53Ga0.47As/InP Quantum Wells at Low Temperatures

The low-temperature electron mobility is investigated here for electrons confined in modulation-doped In0.53Ga0.47As/InP single symmetric quantum wells. The subband structure calculation is developed via variational method, both Schrödinger and Poisson equations being solved simultaneously with adequate heterointerface matching conditions. With this in hands, the main electron scattering rates ...

Silicon Bulk Mobility at High Ambient Temperatures

One of the goals of the PARASITICS project was the evaluation of decisive physical models in the high temperature range (300 K – 700 K) by comparison between simulation and electrical measurements of suitable test structures. Various van der Pauw devices were examined to test the microscopic-based mobility model of Schenk [1]. In order to make the comparison complete, calculated Hall factors as...
