Electron mobility maximum in dense argon gas at low temperature

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...

Electron Mobility in InP at Low Electric Field Application

Temperature and doping dependencies of electron mobility in InP semiconductor has been calculated using an iterative technique. The following scattering mechanisms, i.e, impurity, polar optical phonon, acoustic phonon and piezoelectric are included in the calculation. It is found that the electron mobility decreases monotonically as the temperature increases from 100 K to 600 K. The low tempera...

Gas loading of deuterium in palladium at low temperature

The experimental technique presented in this article is aimed at measuring the absorption of hydrogen or deuterium gas in a thin palladium sample while the system is at low temperature. A result for deuterium is described, consisting in the measurement of the equilibrium loading ratio X (called also D/Pd ratio, atomic), as a function of pressure, on a palladium film 3.6 μm-thick at 150 K.
