According to the band edges A and B shown in Fig.5e, a fractional quantum hall gap can be extracted from the band crossing between the fractional quantum hall flat bandνf = −6 + 1/3 and the Dirac band\({{{\mathrm{L}}}{{{\mathrm{L}}}_{l=-5}^{D}\)(CD = ...
band gap of more than 2.2–2.4eVbecause the quasi-Fermi level lies above and below the respective bands due to the non-radiative recombination, incomplete light trapping, and spontaneous emission[10]. The nonideal alignment of band structure can further reduce the photovoltage. The photophysical ...

(both in contact with their respective current collectors) are located on the same plane with a gap between them to prevent short circuits. The electrolyte permeates the electrodes and fills the gap between the cathode and the anode. In practical application, the cathode and anode of the in-...
18.3.1 Material Band-Gap Energy The electrical properties of atoms are determined by the energy states of the electrons. In a solid with a large number of atoms, electrons of the same energy states form bands, which are organised in levels of ascending energy values. Bands can be either occ...
Fig. 6. Block diagram of RF energy harvesting system. RF energy is an electromagnetic wave signal from the surrounding environment; its sources are TV towers, radio stations, mobile phones, base stations, and wireless networks. Among them, the license-exempt ISM frequency band can be used for...
gap transmitters, for instance, though somewhat inefficient, readily produce short electromagnetic pulses. Delay line pulse generators are well understood in the art to be capable of adjustment such that very short electromagnetic pulses may be radiated. One device for producing such short base-band ...
