Implication

Experimental study demonstrates high-mobility p-type conduction in zinc selenide layers, suggesting improved viability for blue optoelectronic devices.

Key Points

Investigate the electrical and optical properties of p-type zinc selenide layers synthesized by molecular beam epitaxy with nitrogen radical doping.
Grew p-type zinc selenide (ZnSe) crystalline layers via molecular beam epitaxy utilizing nitrogen radical doping.
Fabricated platinum (Pt) contact electrodes to evaluate and minimize contact resistance.
Characterized electrical carrier transport using Hall measurements and optical transitions via room-temperature photoluminescence.
Platinum electrodes markedly reduced contact resistance to the p-type ZnSe layers.
Hall measurements confirmed p-type conduction, exhibiting a carrier concentration of 4.4 × 10^15 cm^-3 and a Hall mobility of 86 cm^2/V·s.
Room-temperature photoluminescence revealed a 2.616-eV emission corresponding to free electron-acceptor hole (FA) recombination, validating p-type behavior.
