Strain-Induced Modulation of the Electronic and Optical Properties of Janus MoSSe Monolayer: A First-principles Study

Kevin C. Ndeche & Azubike J. Ekpunobi · Journal of Materials Science Research and Reviews · 2026

This study investigates the strain-dependent electronic and optical properties of a Janus MoSSe monolayer using first-principles density functional theory calculations incorporating spin-orbit coupling (SOC). In the unstrained structure, the monolayer is a direct-band-gap semicon...

Effects of Normal Load on Nanotribology of Zinc Sulphide (Zns) and Cadmium Sulphide (Cds)

Sunday Isaac Olisakwe, Azubike J. Ekpunobi & Peter I. Ekwo · Current Journal of Applied Science and Technology · 2015

Energetic losses in systems especially miniaturized systems are presently a global challenge. In this work, four new models were developed through a combination of bond orbital model, Tomlinson’s model and Sang’s equation. Using Jump energy models, which is the energy that preven...
