Abstract
Based on the previously-reported porosity multilayer technique, cold electron emission properties of porous silicon (PS) electroluminescent diodes with a structure of Au/PS/n-type Si are further improved by introducing a graded-band multilayer structure. It is shown that electrons are quasiballisticly emitted from PS diodes owing to a significantly reduced electron scattering in PS layer. As a result, the emission current shows a fluctuation-free behavior. These observations are very important for both understanding the electron transport in PS and developing high performance electron emitters in application to vacuum microelectronic technology.Keywords
