Abstract |
Cascade Auger recombination of free carriers on shallow impurities in Ge is investigated under quasi-equilibrium conditions (T= 2-12 K) and in impurity breakdown. The Auger capture cross sections are found to be a,= 5. 10-l9 T-'n cm2 for donors and uip= 7- T-5p cm2 for acceptors. It is shown that in an isotropic semiconductor (p-Ge) ui is well described by the cascade-capture theory that takes into account only electron-electron collisions. In an anisotropic semiconductor ui is considerably larger (n-Ge, strongly uniaxially compressedp-Ge). Under impurity breakdown conditions the electron-electron collisions determine the lifetimes of the free carriers only in samples with appreciable density of the compensating impurity (Nk loi3 cmP3). |

Abstract |
В рамках теории квантовых поправок к проводимости объяснено отрицательное магнитосопротивление в n-Ge с концентрацией доноров Nd≃2.8⋅1016÷1.1⋅1017см−3, наблюдаемое в диапазоне температур 4.2−10 K, когда основной вклад в проводимость дают электроны верхней зоны Хаббарда. Показано, что время релаксации фазы волновой функции τφ определяется временем электрон-фононного взаимодействия τeph. |
