研究了一类具有形状参数的概率密度函数G(a)的性质，它推广了Gumbel分布。当应用于金属-绝缘体-金属结构时，这些函数出现在电荷传输模型中，其中绝缘体由细菌视紫红质单层构成。电流在大约3 V以上急剧增加，解释为直接和注入顺序隧穿机制之间的交叉。特别地，我们证明了随着偏差值的变化，概率密度函数的外观由双峰变为单峰。实际上，双峰分布至少可以在两个不同形状参数值的$g(a)$函数中求解。

英文摘要：
We investigate the nature of a class of probability density functions, say G(a), with a the shape parameter, which generalizes the Gumbel distribution. These functions appear in a model of charge transport, when applied to a metal-insulator-metal structure, where the insulator is constituted by a monolayer of bacteriorhodopsin. Current shows a sharp increase above about 3 V, interpreted as the cross-over between direct and injection sequential-tunneling regimes. In particular, we show that, changing the bias value, the probability density function changes its look from bimodal to unimodal. Actually, the bimodal distributions can be resolved in at least a couple of $G(a)$ functions with different values of the shape parameter.
