Electroluminescence from a n-ZnO nanorod/p-CuAlO2 heterojunction light-emitting diode

Dellafossite CuAlO2 film growth and conversion to Cu–Al2O3 metal ceramic composite via control of annealing atmospheres

“…[1][2][3] The discovery of intrinsic wide bandgap p-type conduction in the dellafossite material CuAlO 2 represents an 25 important step towards realising these technologies. 4 In addition CuAlO 2 as been demonstrated as an effective catalyst for solar water splitting and chlorine production and may also have applications in low power field emission based displays and in sensor technologies.…”

n-ZnO nanorods/p-CuSCN heterojunction light-emitting diodes fabricated by electrochemical method

“…Compared to organic semiconductors, inorganic semiconductors exhibit superior charge transport properties and high chemical stability [8,9]. Indeed, several groups have reported the electroluminescence (EL) from heterojunction LEDs combining n-type ZnO with p-type Si [1,10], SiC [3,4], Cu 2 O [3,4] GaN [11][12][13], CuAlO 2 [14] and CuGaS 2 [15]. However, the fabrication processes mostly involve relatively high temperature and high cost growth methods.…”

The microstructure and photoluminescence of Cu-doped ZnO nano-crystal thin films prepared by sol–gel method

“…As a new type of functional material, ZnO has excellent optical and electrical properties, high chemical and mechanical stability and good heat stability together with nontoxic in nature. With exciton binding energy of 60 meV (the ionization energy of 26 meV at room temperature) and strong ultraviolet stimulated emission, ZnO prepared under different conditions can be applied for various purposes, including laser diodes [1], ultraviolet detectors [2], gas sensors [3], transparent electrode [4,5], electroluminescent material [6,7], surface acoustic wave devices [8], etc. ZnO, following GaN, has become a new focus of the research on the wide band-gap semiconductor.…”
