QUANTUM PLASMAS — SPACE CHARGE LIMITED ELECTRON FLOWS

In this talk, we will discuss the quantum effects of high current space charge limited (SCL) electron flows from field emission in a nangap at both steady state and ultrashort pulse conditions at 1D and 2D models. It is found the traditional models and scaling of field emission law and SCL electron flow (Child-Langmuir law) are no longer when quantum effects become important, such as limiting current density, quantum transit time, electron shot noise, quantum capacitance, etc. The extension of the models to solids with low mobility (like organic materials) will be discussed.
