Direct Determination of Band Gap of Defects in a Wide Band Gap Semiconductor

ACS Applied Materials & Interfaces, 2022
Crystal defects play an important role in the degradation and failure of semiconductor materials and devices. Direct determination of band gap of defects is a critical step for clarifying how the defects affect the physical properties of semiconductors.

A Compact Dual Band Gap Electromagnetic Band Gap Structure

IEEE Transactions on Antennas and Propagation, 2019
In this communication, compact dual-bandgap two via double-slot-type electromagnetic bandgap (TVDS-EBG) structure is presented. The analysis of the TVDS-EBG structure is done by using the $LC$ model. Two resonance parallel $LC$ circuits per unit cell result dual-bandgap in the $x$ - and $y$ -directions.

Band-gap renormalization in quantum wires

Physical Review B, 1993
The carrier density dependence and the temporal evolution of the ground level parameters of a quasi-one-dimensional electron-hole plasma confined in GaAs quantum wires have been studied by a line-shape analysis of the time-resolved luminescence.

Density-Functional Theory of the Band Gap

Physical Review B, 1985
Publisher Summary This chapter discusses the density-functional theory (DFT) of the band gap. Emphasizing the dependence of the density functionals on the number of particles brings out the difference between the highest occupied energy of the (N +1)-particle system and the (N + 1) th level of the N-particle system.

Band Gap of Forsterite

Science, 1968
Optical absorption and reflectivity measurements on synthetic forsterite show that this silicate has a wide band gap of the order of 8.4 electron volts; thus it resembles other pure insulating oxides such as MgO. For natural olivines, in which divalent cations, mainly Fe 2+ , can replace Mg 2+
