Room Temperature Ultraviolet Electroluminescence from Poly(methylphenylsilane)

Abstract

Abstract Using carefully purified poly(methylphenylsilane) (PMPS), we have successfully fabricated PMPS LEDs which emit UV light at room temperature for the first time. The study of I-V characteristics of PMPS LEDs indicates that Trapped-Charge-Limited (TCL) currents dominate the charge transport in LEDs at high current region.
