Fabrication of In₂O₃(ZnO)_m superlattice microplates with hexagon morphologies

In₂O₃(ZnO)_m microplates possessed a superlattice structure with a large m number i.e. m=23, consisting of layered alternating stacks of octahedral InO₂^– as inversion boundaries and layered InZn_mO_m₊₁⁺ as a zig-zag modulated pattern.
Negative thermal quenching (NTQ) of PL emission occurred in the temperature range from 100 to 120 K.
The anisotropic electrical properties of In₂O₃(ZnO)_m were manifested, for the first time

Design and built a set of laser-induced growth device

Based on the results of finite element analysis (by COMSOL Multiphysics), the device was built with multiple-laser heating system (1080 nm and 2500W).
Acceptor-rich ZnO single crystal microrods with complete hexagonal cross-section morphology were successfully prepared by the growth device.

Development of local-dimming algorithm

Designed and simulated a local dimming backlight control system for display screens using Visual Studio.

DFT calculation of AlInO alloy

AlInO with 37.5% In content was identified as a potentially lattice-matched material with β-Ga₂O₃
AlInO alloys exhibits 5.59 eV tuning range for corundum-based structure and 4.91 eV for monoclinic-based structure
Band alignment in AlInO/β-Ga₂O₃ structure exhibits both type-I and type-II band offset among the whole composition range.

Ion Implantation and DFT Calculation of Point Defects

Investigated the effects of ion implantation at different doses on oxides, focusing on damage stimulation and defect formation mechanisms.
Studied the impact of annealing temperature on the samples, observing changes in defect characteristics.
Conducted DFT calculations to understand the formation and behavior of point defects induced by ion implantation.
