Changes in the input voltage lower the barrier and increase current flow in transistors, just as adding an enzyme to a chemical reaction speeds it up.

改变输入电压能降低屏障并增加晶体管电流，正如加入酶使化学反应加速一样。

The effective barrier changes with increasing applied voltage, and there is a step in the current of barrier vs voltage.

研究了场发射的有效势垒随外加电场的变化，发现在有效势垒随外电场变化的曲线中存在一段平台。
