Related to bandgap: Photonic bandgap


The difference in energy between electron orbitals in which the electrons are not free to move (called valence bands) and orbitals in which they are relatively free and can carry a current (called conduction bands).

The researchers say that material's relatively large bandgap compared to silicon makes it a prime candidate to serve as the top layer in a tandem solar cell.
However, the tight lattice lacks a semiconducting bandgap, which is essential for electronic devices.
Low process temperature and, as a result, more economic modules [1], high open circuit voltage due to higher bandgap of amorphous silicon [2], good efficiency due to low recombination of carriers in the interface of amorphous and crystalline silicon [3], good stability and low temperature dependence [1] are of advantages of these solar cells.
This ALD tool enables advances in our research for high-performance CMOS, nonvolatile memory, next-generation wide bandgap power devices, and environmental and physiological sensors.
So far, most materials with a wide bandgap have been found to have either low conductivity or poor transparency.
The various types of electromagnetic bandgap structure are available for the antenna applications.
Hall-effect switches utilize a chopper-stabilized architecture with an internal bandgap referenced to achieve reliable operation over a wide -40[degrees]C to +125[degrees]C temperature range with minimal switching point drift

Wolfspeed Wide Bandgap Automotive Traction Inverter converts the direct current (DC) power stored in either a hybrid, plug-in hybrid or all-electric vehicle battery pack to a three-phase alternating current power used to energize one or more electrical loads.
It helps drive the transition from bulky Silicon systems to high-density Silicon Carbide power electronic systems that can operate at higher efficiencies, higher voltages, higher power densities, and higher temperatures than conventional silicon electronics, and to create the first optimized package for wide bandgap semiconductors.
Department of Energy, industry and academia, has released a new call for projects to advance wide bandgap (WBG) semiconductor manufacturing and to accelerate the adoption of WBG semiconductor power electronics applications.
