The possible importance of zinc-oxide-based optoelectronic devices is reviewed in this paper, which places special emphasis on the need to achieve p-type ZnO. ABSTRACT | ZnO is an attractive material for applications in electronics, photonics, acoustics, and sensing. In optical emitters, its high exciton binding energy (60 meV) gives ZnO an edge over other(More)
The observation of ferromagnetism in magnetic ion doped II–VI diluted magnetic semiconductors (DMSs) and oxides, and later in (Ga,Mn)As materials has inspired a great deal of research interest in a field dubbed " spintronics " of late, which could pave the way to exploit spin in addition to charge in semiconductor devices. The main challenge for practical(More)
— Although started as red indicator lights based on the GaP:N system, replacing only the nixie (Numeric Indicator eXperimental No. 1) tube, LEDs have become quite a high performance device of late and are revolutionizing the display and illumination sectors of our economy. Presently, the GaN based light emitters adorn the automobiles, traffic lights, moving(More)
Compact and efficient sources of blue light for full color display applications and lighting eluded and tantalized researchers for many years. Semiconductor light sources are attractive owing to their reliability and amenability to mass manufacture. However, large band gaps are required to achieve blue color. A class of compound semiconductors formed by(More)
