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。

Based on the model, the variations of the electrical parameters such as the potential barrier, the anode junction voltage drop, and the current amplification factor are studied and discussed.
