AbstractThe electronic, magnetic, and optical properties of graphene (gr) containing selenium impurities of 2, 3, 5.5, and 12.5% were calculated by DFT. By increasing the percentage of Se impurity, the energy gap decreases from about 0.3 eV for the gr+Se(2%), to about 0.1 eV for gr+Se(3%) monolayer. Continuing this trend leads to metallic property ...

AbstractHybrid organic-inorganic halide perovskites as promising solar cell materials have great concern on their stability. Recently, all-inorganic perovskite CsPbI2Br has been considered as a first-class alternative with good stability as well as a suitable bandgap, and the highest solar cell efficiency has been achieved up to 16%. Using the firs...

Accurate reference dielectric functions play an important role in the research and development of optical materials. Libraries of such data are required in many applications in which amorphous semiconductors are gaining increasing interest, such as in integrated optics, optoelectronics or photovoltaics. The preparation of materials of high optical ...

In order to reach the theoretical efficiency limits of lead-based metal halide perovskite solar cells, the voltage should be enhanced because it suffers from non-radiative recombination. Perovskite materials contain intrinsic defects that can act as Shockley&ndash / Read&ndash / Hall recombination centers. Several experimental and computational stu...

Anthracene-based semiconductors have attracted great interest due to their molecular planarity, ambient and thermal stability, tunable frontier molecular orbitals and strong intermolecular interactions that can lead to good device field-effect transistor performance. In this study, we report the synthesis of six anthracene derivatives which were di...

In this thesis, we investigate the optical properties of excitonic quasiparticles in different transition metal dichalcogenides (TMDCs). These novel two-dimensional (2D) semiconductor materials exhibit remarkable mechanical, optical and electronic properties and feature an additional valley degree of freedom. Due to their atomically thin nature, ex...

Possessing a large surface-to-volume ratio is significant to the sensitive gas detection of semiconductor nanostructures. Here, we propose a fast-response ammonia gas sensor based on porous nanostructured zinc oxide (ZnO) film, which is fabricated through physical vapor deposition and subsequent thermal annealing. In general, an extremely thin silv...
