Abstract
En 中文
In a III-nitride multiple quantum well (MQW) diode biasedwith a forward voltage, electrons recombine with holes inside theMQW region to emit light; meanwhile, the MQW diode utilizes the photoelectriceffect to sense light when higher-energy photons hit the device todisplace electrons in the diode. Both the injected electrons and theliberated electrons are gathered inside the diode, thereby givingrise to a simultaneous emission-detection phenomenon. The 4 x4 MQW diodes could translate optical signals into electrical onesfor image construction in the wavelength range from 320 to 440 nm.This technology will change the role of MQW diode-based displays sinceit can simultaneously transmit and receive optical signals, whichis of crucial importance to the accelerating trend of multifunctional,intelligent displays using MQW diode technology.
