Using density functional theory coupled to the Boltzmann transport equation with relaxation time approximation, we study electronic structure and carrier mobility of graphene-like hexagonal boron phosphide (h-BP) monolayer H-terminated armchair nanoribbons (ABPNRs). Our results show that can reach over 104 cm2 V–1 s–1 for electron 5 × 103 hole in sheet. The ABPNRs is range s–1, find width nanoribbon plays an important role tuning polarity transport, which exhibits a distinct 3p (p positive...
Understanding the photoexcited carrier-relaxation actions in ultrasmall black phosphorus quantum dots (BPQDs) will play a crucial role fields of electronics and optoelectronics. Herein, we report ultraviolet (UV) saturable absorption ultrafast dynamics BPQDs. The BPQDs are synthesized using facile liquid-exfoliation method possess diameter 3.8 ± 0.6 nm thickness 1.5 0.4 nm. Femtosecond open-aperture (OA) Z-scan measurements showed typical properties UV band. A negative nonlinear optical...
We propose an ab initio Boltzmann transport approach taking into account magnon-phonon scattering (MPS) and three-phonon simultaneously to accurately evaluate the thermal properties of ferromagnetic crystals. Using this approach, we studied nonelectronic body-centered cubic iron as a case. The reasonable agreement between our calculation results available experimental data suggests that phonons dominate conduction at high temperatures, magnons may contribute conductivity only low...
We report two nondegenerate magnon modes with opposite spins or chiralities in collinearly antiferromagnetic insulators driven by symmetry-governed anisotropic exchange couplings. The consequent giant spin splitting contributes to Seebeck and Nernst effects generating longitudinal transverse currents when the temperature gradient applies along away from main crystal axis, without requiring any external magnetic field spin-orbit coupling. Based on first-principle calculations, we predict...
Biodegradability is one of the most critical issues for silica-based nanodrug delivery systems because they are crucial prerequisites successful translation in clinics. In this work, a novel mesoporous silica–calcium phosphate (MS–CAP) hybrid nanocarrier with fast pH-responsive biodegradation rate was developed by one-step method, where CAP precursors (Ca2+ and PO43–) were incorporated into silica matrix during growth process. The morphology structure MS–CAP characterized scanning electron...

Two-dimensional monolayer Tellurium, termed as Tellurene (Te), has recently been fabricated in the experiment. In this work, under uniaxial strain applied along either armchair or zigzag direction with strength varying from 0 to 40%, we have investigated mechanical property of Te including three allotropes (α-Te, β-Te, and γ-Te). Our results show that β-Te exhibits most obvious anisotropy stress-strain curve, Young's modulus, Poisson's ratio, which is thought originate its inherent structure...

The non-Hermitian Aharonov-Bohm (AB) cage is a unique localization phenomenon that confines all possible excitations. This confinement leads to fully flat spectrum in momentum space, which are typically accompanied with the degeneracy various types. Classifying type crucial for studying dynamical properties of AB cage, but methods such classification and their physical connections remain not very clear. Here, we construct bosonic Bogoliubov-de Gennes (BdG) system degenerate bands (DFBs)....

Two-dimensional semiconductors are considered as promising channel materials for next-generation nanoelectronics devices, while their practical applications typically limited by low mobilities. In this work, using first-principles calculations combined with the Boltzmann transport formalism involving electron–phonon coupling, we study properties of monolayer group-IV monochalcogenides (MX, M = Ge, Sn; X S, Se, and Te). We find that GeTe SnTe possess exceptionally high hole mobilities, which...
