“势垒区”常见的英文表达是 "barrier region" 或 "potential barrier region"。
在半导体物理、量子力学等领域中,这两个表述都较为常用,具体可根据语境和学科习惯进行选择。例如:
In a semiconductor diode, the barrier region is where the electric field is concentrated. (在半导体二极管中,势垒区是电场集中的区域。)
The potential barrier region plays a crucial role in determining the current flow through the device. (势垒区在决定器件电流流动方面起着关键作用。 )
