First-Principles Calculations on Structural Property and Anisotropic Elasticity of ₁-Ti₄Nb₃Al₉ under Pressure.

The effect of pressure on the structural property and anisotropic elasticity of γ 1 -Ti 4 Nb 3 Al 9 phase has been investigated in this paper by using first-principles calculations. The obtained bulk properties at zero pressure are in good agreement with the previous data. The structural property and elastic constants under pressures up to 40 GPa have been obtained.

Pressure Effect on Elastic Constants and Related Properties of Ti₃Al Intermetallic Compound: A First-Principles Study.

Using first-principles calculations based on density functional theory, the elastic constants and some of the related physical quantities, such as the bulk, shear, and Young's moduli, Poisson's ratio, anisotropic factor, acoustic velocity, minimum thermal conductivity, and Debye temperature, are reported in this paper for the hexagonal intermetallic compound Ti 3 Al. The obtained results are well consistent with the available experimental and theoretical data. The effect of pressure on all studied parameters was investigated.

Narrowband ultraviolet photodetector based on MgZnO and NPB heterojunction.

An ultraviolet photodetector was fabricated based on Mg0.07Zn0.93O heterojunction.

High response organic deep ultraviolet photodetector with PEDOT:PSS anode.

We have fabricated an organic deep ultraviolet photodetector (PD) using PEDOT:PSS (PH 1000) as a transparent anode. NPB and PBD were employed as electron donor and acceptor, respectively. The PD exhibits a dark current of 0.
