Heterojunctions have received much interest as a way to improve semiconductors' electrical and optical properties. The impact of the interface on properties g-C3N4/SnS2 was explored using first-principles calculations in this study. results show that, at hetero-interface, conventional type-II band forms, resulting lower gap than that g-C3N4 SnS2 monolayers. When there is no high barrier height, averaged microscopic macroscopic potentials can be used accomplish efficient carrier...

Using first-principles calculations, we investigate the structural, electronic, and magnetic properties of perovskite LaMO3/YMO3 superlattices (M = Cr, Mn, Co Ni). It is found that ferroelectricity can emerge in Co), allowing them to be promising multiferroic candidates, while no LaNiO3/YNiO3 superlattice. The electronic structure calculations indicate LaCrO3/YCrO3, LaMnO3/YMnO3, LaCoO3/YCoO3 are insulators, their ground states exhibit G-type antiferromagnetic (AFM), A-type AFM, AFM order,...

Abstract An easy synthetic route to N -dichloroacetyl-3,4-dihydro-2 H -1,4-benzoxazine derivatives 3 involves cyclization of 2-aminophenols 1 with 1,2-dibromoethane and subsequent acylation the resultant 3,4-dihydro-2 2 dichloroacetyl chloride. All compounds were characterized by IR, NMR, 13 C ESI-MS elemental analysis. The structure 3a was determined X-ray crystallographic

We report first-principles calculations on the structural, mechanical, and electronic properties of O2 molecule adsorption different graphenes (including pristine graphene (G–O2), N(nitrogen)/B(boron)-doped (G–N/B–O2), defective (G–D–O2)) under equibiaxial strain. Our calculation results reveal that G–D–O2 possesses highest binding energy, indicating it owns stability. Moreover, stabilities four structures are enhanced enormously by compressive strain larger than 2%. In addition, band gaps...

Boron nitride structures have excellent thermal and chemical stabilities. Based on state-of-art theoretical calculations, we propose a wide-gap semiconducting BN crystal with three-dimensional hyperhoneycomb structure (Hp-BN), which is both mechanically thermodynamically stable. Our calculated results show that Hp-BN has higher bulk modulus smaller energy gap as compared to c-BN. Moreover, due the unique bonding structure, exhibits anisotropic electronic optical properties. It great...

We investigate mechanical, structural and electronic properties of CO2 adsorbed graphitic carbon nitride (g-C3N4) system under biaxial tensile strain via first-principles calculations. The results show that the stress g-C3N4 increases then decreases linearly with increasing strain, reaching maximum at 0.12 strain. This is primarily caused by plane N–C stretching g-C3N4. Furthermore, both Perdew-Burke-Ernzerhof (PBE) Heyd- Scuseria-Ernzerhof screened hybrid functional (HSE06) band gaps...
