Abstract :
Summary form only given. This work presents a simple short-pulse model of space-charge-limited (SCL) current density or Child-Langmuir (CL) law in both quantum and relativistic regimes. When the pulse length is confined to femtosecond duration, corresponding to the pulse size of nanometer scale, quantum mechanical effects such as the electron tunneling through the space-charge potential, and the electron exchange-correlation interaction become important that the classical short-pulse CL law is no longer valid.
