Compared with the two-dimensional atomic crystal materials whose bulk phase is layered originally, related research of material crystals non-layered still very scarce. The monolayer CuSe studied in this paper belongs to latter, which a new honeycomb graphene analogue. Monolayer not suitable for application electronic devices because its metallic nature. In order find excellent performance devic...
Photosensitized oxidations or reductions at pand n-type GaAs and InP semiconductor electrodes of aromatic species in aprotic solvents leading to electrogenerated chemiluminescence (ECL) are described. The energy of the irradiating light equal to the bandgap energy of the semiconductor and the electrical energy input couple to produce excited states which eventually produce emission at shorter w...
Using density functional theory calculations, we study the electronic and magnetic properties of the p-type monolayer II-VI semiconductors SrX (X = S,Se). The pristine SrS and SrSe monolayers are large band gap semiconductor with a very flat band in the top valence band. Upon injecting hole uniformly, ferromagnetism emerges in those system in a large range of hole density. By varying hole densi...
The synthesis of one-dimensional van der Waals heterostructures was realized recently, which opens up new possibilities for prospective applications in electronics and optoelectronics. even reduced dimension will enable novel properties further miniaturization beyond the capabilities its two-dimensional counterparts have revealed. natural doping results p-type electrical characteristics semicon...
Pyrite is a common sulfide mineral in gold deposits, and its unique thermoelectricity has received extensive attention the field of exploration. However, there still lack detailed research direct evidence about how impurity elements affect semiconductor properties. In this paper, combined with first-principles calculations, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS)...
We study the electromechanical response of Janus transition metal dichalcogenide (TMD) nanotubes from first principles. In particular, considering both armchair and zigzag variants twenty-seven select TMD nanotubes, we determine change in bandgap charge carriers' effective mass upon axial torsional deformations using density functional theory (DFT). observe that metallic remain unaffected, wher...
Compound semiconductor devices, as typified by laser diodes, photo diodes, and high electron mobility transistors, are used for optical communication systems, satellite communications, and cellular base stations to meet a growing demand for large-capacity and high-speed communication systems that play a key role in the infrastructure of modern society. The properties and reliability of semicond...
In this paper, we report a new structure for bipolar junction transistors based on concept of surface inversion. This structure is made up of only one PN junction and a metal with appropriate work function connected to the p region which results in an inversion of electrons in the semiconductor near the metal-semiconductor interface, this inversion layer plays the role of emitter n+ region. Sim...
