Taiwanese scientists develop high-efficiency silicon LED heterostructure
Date:2010-11-24 16:04
According to Taiwan media reports, the silicon microelectronics industry is the most commonly used material, but because of its indirect energy band (indirect bandgap), luminous efficiency is very low. Recently, the National Taiwan University Department of Materials Science and Engineering, and Professor Yang Zheren Professor Chen Minzhang led research team, using n-type zinc oxide / silicon dioxide - silicon nano ceramic - silica / p-type Si substrate (n- ZnO/SiO2-Si nanocrystal-SiO2/p-Si) of t
