Method for estimating elastic modulus of doped semiconductors by using ab initio calculations—Doping effect on Young’s modulus of silicon crystal

open access: yesAIP Advances, 2023
A novel method for estimating the elastic modulus of doped semiconductors using ab initio calculation is demonstrated for a Si crystal. The elastic modulus of various materials basically depends on lattice constants on which dependence is shown by ab ...

Opacity data for HCN and HNC from a new ab initio line list [PDF]

open access: yes, 2002
A new extensive ab initio rotation-vibration HCN/HNC line list is presented. The line list contains rotation-vibration energy levels, line frequencies, and line strengths for transitions between states with energy less than 18,000 cm-1 and with J≤60 ...

Ab-Initio Calculations [PDF]

open access: yes, 2017
Due to the difficulties found in the direct solution of the Schrodinger equation, different simplified approaches were proposed and are nowadays widely used. Among them, those most usually employed are the Hartree–Fock and the Density Functional Theory, which we revisit in the present chapter.

Intrinsic Nanopore‐Assisted SnP2S6 Memristors With Ti Ion Dynamics for Compact Logic‐In‐Memory Hardware

open access: yesAdvanced Functional Materials, EarlyView.
Tin hexathiophosphate memristors leverage intrinsic nanopores together with a guided filament formation strategy to regulate titanium ion motion and switching behavior. The devices support reliable nonvolatile memory and reconfigurable logic‐in‐memory, demonstrating 14 Boolean logic functions in a single cell.

Discovering charge density functionals and structure-property relationships with PROPhet: A general framework for coupling machine learning and first-principles methods

open access: yesScientific Reports, 2017
Modern ab initio methods have rapidly increased our understanding of solid state materials properties, chemical reactions, and the quantum interactions between atoms. However, poor scaling often renders direct ab initio calculations intractable for large

Resolution of ab initio shapes determined from small-angle scattering

open access: yesIUCrJ, 2016
Spatial resolution is an important characteristic of structural models, and the authors of structures determined by X-ray crystallography or electron cryo-microscopy always provide the resolution upon publication and deposition. Small-angle scattering of

First-principles investigation of the Ni-Fe-Al system

open access: yes, 2004
By combining ab-initio electron theory and statistical mechanics, the physical properties of the ternary intermetallic system Ni-Fe-Al in the ground state and at finite temperatures were investigated. The Ni-Fe-Al system is not only of high technological
