论文摘要
在空间相关的状态密度（DOS）的无定形半导体中，已考虑用于随机能量的相关函数的任意行为。对于准平衡（非分散性）运输状态，精确计算了平均载流速度。对于具有指数尾巴的对称指数DOS，低能和高能量和非阳性相关函数的指数尾巴过渡到分散运输方案的温度取决于相关性能，并且基于DOS衰减能量$ kt = u_0 $，基于DOS衰减能量的传统估计。具有非阳性相关函数的景观中传输的另一个新特征是在低场区域的轨道衰减。
Charge transport in amorphous semiconductors having spatially correlated exponential density of states (DOS) has been considered for the arbitrary behavior of the correlation function of random energies. Average carrier velocity is exactly calculated for the quasi-equilibrium (nondispersive) transport regime. For the symmetric exponential DOS with exponential tails for low and high energies and non-positive correlation function the temperature for the transition to the dispersive transport regime depends on correlation properties and becomes greater than the traditional estimation based on the DOS decay energy $kT=U_0$. Another new feature of the transport in the landscape having non-positive correlation function is the decay of the mobility with field in low field region.
