A Compact Dual Band Gap Electromagnetic Band Gap Structure
IEEE Transactions on Antennas and Propagation, 2019In 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.

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+

Band-gap renormalization in quantum wires
Physical Review B, 1993The 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, 1985Publisher 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.

Mobility Gaps: A Mechanism for Band Gaps in Melanins
Science, 1972The semiconductor behavior of melanins is reviewed and compared with quantum mechanical models of conduction in amorphous solids. The available data are consistent with extensions of Mott's basic model for amorphous semiconductors, whereas they are inconsistent with crystalline semiconductor models.
