Embodiment

[0017] 1) Take ZnO, MgO and P with a purity of 99.99% 2 o 5 Powder, wherein the molar content of MgO is 20%, that is, the molar ratio of MgO:ZnO is 1:4, P 2 o 5 The molar content is 0.1%. Then ZnO, MgO and P 2 o 5 The powder is mixed and poured into an agate ball cup, and placed on a ball mill for ball milling. On the one hand, ZnO, MgO and P can be 2 o 5 The powder is mixed evenly to ensure the uniformity of the prepared target. On the other hand, ZnO, MgO and P 2 o 5 Powder refinement for subsequent ZnO, MgO and P 2 o 5 Forming and sintering of mixed powders. After the ball milling, add the binder polyvinyl acetate, and press the powder into a disc with a thickness of 3mm and a diameter of 4cm; then sinter the pressed powder disc at 500°C for 1 hour to form an organic bond. The agent evaporates, and the P-doped 2 o 5 Zn 0.8 Mg 0.2 O ceramic target.

Abstract

A process for preparing the p-type Zn1-xMgxO crystal film includes providing high-purity ZnO, MgO and p-type dopant powder, proportional mixing, grinding, adding organic adhesive, die pressing, sintering to obtain p-type doped Zn1-xMgxO ceramic target, and using laser to irradiate the ceramic target in high-purity oxygen to grow th p-type Zn1-xMgxO crystal film on clean substrate.

Description

technical field [0001] The present invention relates to p-type doped Zn 1-x Mg x O crystal thin film and its preparation method. Background technique [0002] Zn 1-x Mg x O ternary alloy is a solid solution formed by ZnO and MgO according to a certain composition. In the application of ZnO-based light-emitting and optoelectronic devices, it is necessary to prepare p-Zn in order to improve the luminous efficiency of the device. 1-x Mg x O / ZnO / n-Zn 1-x Mg x O quantum well, superlattice structure, growth controllable n and p type Zn 1-x Mg x O crystal film. However, only intrinsically undoped Zn 1-x Mg x O thin film, no p-type Zn yet 1-x Mg x O crystal thin films, for intrinsically undoped Zn 1-x Mg x The preparation methods of O thin films mainly include: metal organic chemical vapor deposition (MOCVD), molecular beam epitaxy (MBE), pulsed laser deposition (PLD), etc. 1-x Mg x The p-type doping technology of O crystal thin film has ...
