Phase Diagram and High-Temperature Superconductivity of Compressed Selenium Hydrides [PDF]

Sci. Rep. 5, 15433 (2015), 2015
Recent discovery of high-temperature superconductivity (Tc = 190 K) in sulfur hydrides at megabar pressures breaks the traditional belief on the Tc limit of 40 K for conventional superconductors, and open up the doors in searching new high-temperature superconductors in compounds made up of light elements. Selenium is a sister and isoelectronic element

MoSSe Janus monolayer as a promising two dimensional material for NO2 and NO gas sensor applications [PDF]

, 2018
Gas sensing mechanism of H2S, NH3, NO2 and NO toxic gases on transition metal dichalcogenides based Janus MoSSe monolayers are investigated using the density functional theory. The pristine and defect included MoSSe layers are considered as a host material for adsorption study.

An Overview of Selenium Uptake, Metabolism, and Toxicity in Plants

Frontiers in Plant Science, 2017
Selenium (Se) is an essential micronutrient for humans and animals, but lead to toxicity when taken in excessive amounts. Plants are the main source of dietary Se, but essentiality of Se for plants is still controversial.

Selective crystal growth of indium selenide compounds from saturated solutions grown in a selenium vapor [PDF]

arXiv, 2021
Indium selenide compounds are promising materials for energy conversion, spintronic applications, and chemical sensing. However, it is difficult to grow stoichiometric indium selenide crystals due to the high equilibrium selenium vapor pressure and the complicated phase equilibrium system of indium selenide compounds.

Increasing the Collection Efficiency in Selenium Thin-Film Solar Cells Using a Closed-Space Annealing Strategy [PDF]

ACS Appl. Energy Mater. 2024, 7, 12, 5209-5215
Elemental selenium is a promising wide-bandgap ($E_\mathrm{G}\approx$ 1.95 eV) photovoltaic material for the next generation of thin-film solar cells. To realize high-efficiency selenium solar cells, it is crucial to optimize the crystallization process of the selenium thin-film photoabsorber.
