Experimental analysis reveals high electron Hall mobility in silver chloride crystals at low temperatures, indicating distinct acoustic phonon and impurity scattering mechanisms.

Key Points

Measure the Hall mobility of photoelectrons in single crystals of silver chloride down to 5 K to evaluate electronic transport and scattering mechanisms at low temperatures.
Measured photoelectron Hall mobility down to 5 K in single crystals of silver chloride using a specialized pulse technique.
Addressed experimental challenges of space-charge accumulation and high electrical impedance inherent to insulating crystals.
Evaluated temperature-dependent mobility and magnetoresistance data against theoretical models of optical, acoustical, and impurity-induced lattice scattering.
Electron Hall mobility increased to 6000 cm²/volt-sec at very low temperatures, whereas drift mobility was strongly suppressed by multiple trapping.
Electron scattering was dominated by optical and acoustical lattice vibration modes across distinct temperature ranges, with structure-dependent impurity scattering appearing below 20 K.
Magnetoresistance effects increased significantly at high mobilities and magnetic fields, aligning with electronic conductivity theory for simple-band cubic crystals.
