摘要: Abstract The present investigation highlights the structural, thermodynamic, electronic, and optical properties of WC (Bh) phase ZnO calculated by means first principles Debye model approach. Acquired results revealed that pressure-induced transitions followed sequence (B4 → WC → B2). trend thermodynamic with temperature pressure has been discussed. Hybrid Functional (B3LYP) was employed to explore bands properties. band gap under is fitted well a quadratic equation. Calculations demonstrate an increase in increasing leads blue shift validates insulator, whereas negative real part dielectric function e1(ω) indicates it possesses metallic behaviour at around 21.9 & 23.5 eV. relation between absorption constant examined detail. This exploration demonstrates potential for technological applications.
