Dislocation engineering for a silicon-based light emitter at 1.5 /spl mu/

摘要

A new concept for a Si light emitting diode (LED) capable of emitting at 1.5 mum efficiently is proposed. It utilizes radiation from a well-defined dislocation network created in a reproducible manner by Si wafer direct bonding. The wavelength of the light emitted from the network can be tailored by adjusting the misorientation between the Si wafers
