1.If the emitter ledge is too thick, current will flow through the undepleted ledge, which increases the emitter-size effect.
不适当的射极突出部厚度,将会在射极突出部侧壁造严重的表面复合。
2.The analytical solutions for the stead state equations of four wave mixing with an arbitrary complex coupling constant are given without the undepleted pump approximation.
