The energy (and thus the color of the light) is determined by the energy gap, Eg, between the two bands. Simple models of band theory, such as the Kronig–Penney model, the Ziman model, and the Feynman model, g

To exemplify the implementation of the above method, four different monolayer 2D materials with contrasting band structure and conductivity: h-BN (wide-gap semiconductor) [87], graphene (zero-gap semiconductor) [88], g-C3N4 (semiconductor with a band gap of 1.87 eV) [89] and g-C4N3 (half...

a larger breakdown voltage can be applied in SiC device without increasing the on-state resistance. As the thermal conductivity is also 3 times larger the heat dissipation is more. The wide energy band gap stops the electrons to move to the conduction band making the leakage current lower even...
The conversion efficiency in a Si solar system, which is still the traditional module, with a band gap of 1.1 eV, can achieve a value of 33.7%. The spectral mismatch between the photon energy of the incident solar spectrum and the band gap of the material used into the module degrades ...
For the 28 nm CMOS process, the n-type metal–oxide–semiconductor (NMOS) transistor transition frequency (ft) could reach 270 GHz, with the gate (VG) and drain (VD) biased at 0.7–0.8 V. Similarly, the bandwidth of a very short length of the modulator (in the depletion ...
