The main objectives here can be divided roughly into two parts. The first part will be studies of electronic structures of the materials of interest to gain better understanding of their properties microscopically. Then for, the second part, we will attempt to fabricate simple devices which demonstrate the unique properties of the studied materials. More details are as below:
1(a). The electronic-structure study of dichalcogenides (e.g. MoS2, WSe2, PdTe2) will focus on their spin nature, band gap and superconductivity.
1(b). The electronic-structure study of oxides (e.g. titanium-oxide-based and tantalum-oxide-based compounds ) will focus on their spin texture, band-gap shrinkage effect and light-sensitive properties of the two-dimensional conducting layer (2DEG) at the surface.
1(c). The electronic-structure study of carbon-based materials (e.g. diamondoid and graphene) will focus on the measurement of electron affinity and search for any signature of superconductivity.
2. Attempt to create new devices which can demonstrate novel functionalit(ies) or improve performance of available devices. Examples include: light-sensitive capacitor, light-sensitive spintronics, thermoelectric generator and solar cell
