我们分析了决定共振隧穿输运的两个因素的性质：一维载流子能量分布因子，其随能量单调减小并随温度增加，以及透射概率峰，其随偏压和温度减小，并且我们确定了电流共振的判据。我们的结论与通常的描述有很大的不同。用常数EF、μ和m * 计算共振隧穿随温度的变化，不能给出峰值电流随温度的减小
We analyzed the properties of the two factors determining the resonant-tunneling transport: the one- dimensional carrier energy distribution factor, which monotonically decreases with energy and increases with temperature, and the transmission probability peak, which decreases with bias and temperature, and we determined a criterion for current resonance. Our conclusions are quite different from those in commonly used descriptions. Calculations of the resonant tunneling versus temperature with constant E F , μ, and m * cannot give a decrease of peak currents with temperature
