Space-Charge-Limited Current in Quantum Regime by Solving the Schr枚dinger-Poisson Equation Based on Finite Element Method

摘要

The Child-Langmuir law gives the maximum electron current, known as the space-charge- limited current. In a previous work of Lau et ah, they extended the classical work of Child and Langmuir to the quantum regime by using the Wentzel-Kramers-Brillouin-Jef
