Field-Induced Conductivity Changes in Germanium

摘要: Variations in the conductance of a germanium filament due to an electric field normal surface were measured for fields up ${10}^{5}$ volts/cm. Observation minimum curve makes it possible calculate charge states as function potential. Information this sort obtained with several gaseous ambients is compared Brattain-Bardeen observations on contact Measurements temperature down 170\ifmmode^\circ\else\textdegree\fi{}K give information about properties "fast" states. Phase shift loops observed at frequencies around kilocycle are interpreted terms minority carrier lifetime. low temperatures believed be traps.
