We present a nonlinear model of thermal field emission in resonant tunneling nanostructures with multiple barriers and potential wells, based on an accurate determination of the quantum potential shape and a rigorous solution of the Schrödinger equation, while considering thermal balance. The model applies to vacuum and semiconductor resonant tunnel diode and triode structures with two and three electrodes and to the general case of two-way tunneling with electrode heating. The complete balance of heat release and transfer is accounted for, with heat transport considered ballistic. This approach can also be extended to the non-stationary case, incorporating the influence of space charge. The short flight time of electrons in such structures makes them promising for the fabrication of THz devices.
我们基于对量子势形状的精确确定以及薛定谔方程的严格求解，同时考虑热平衡，提出了一种具有多个势垒和势阱的共振隧穿纳米结构中的热场发射非线性模型。该模型适用于具有两个和三个电极的真空和半导体共振隧道二极管及三极管结构，以及电极加热情况下的双向隧穿一般情形。考虑了热释放和传递的完全平衡，热传输被视为弹道传输。这种方法还可以扩展到非稳态情况，纳入空间电荷的影响。此类结构中电子的短飞行时间使其有望用于制造太赫兹器件。
