Structure and binding in halide perovskites: Analysis of static and dynamic effects from dispersion-corrected density functional theory

open access: yesAPL Materials, 2019
We investigate the impact of various levels of approximation in density functional theory calculations for the structural and binding properties of the prototypical halide perovskite MAPbI3. Specifically, we test how the inclusion of different correction

Structural, Electronic, and Optical Properties of HgSe Monolayer: Density Functional Theory Calculations

open access: yesIraqi Journal of Physics
To investigate the structural, electrical, and optical properties of a single layer of two-dimensional mercury selenide (HgSe), density functional theory is used for the analysis of the material.

Triboelectric Charging Properties of the Functional Groups of Common Pharmaceutical Materials Using Density Functional Theory Calculations

open access: yesPharmaceutics
Triboelectrification is a ubiquitous and poorly understood phenomenon in powder processing, particularly for pharmaceutical powders. Charged particles can adhere to vessel walls, causing sheeting; they can also cause agglomeration, threatening the ...
