Local Charge

It is demonstrated in this paper that, in terms of a schematic multiperipheral model, net charge fluctuation satisfies the same Quigg–Thomas relation as satisfied by charge transfer fluctuation. Net charge fluctuations measured in finite rapidity windows depend on both the local charge correlation length and the size of the observation window. When the observation window is larger than the local charge correlation length, the net charge fluctuation only depends on the local charge correlation length and can be used as a measure of local charge correlation length.

Thin Barrier

In this paper, a novel, GaN-based high electron mobility transistor (HEMT) using an ultra-thin barrier (UTB) with a local charge compensation trench (LCCT) is designed and optimized. Because the negative plasma-etching process, as well as the relaxing lattice during the process would introduce equivalent negative charges into the under-LCCT region, the electron will be partially squeezed out from this area. The electric field (E-field) around this region will therefore redistribute smoothly. Owing to this, the proposed LCCT-HEMT performs better in power applications. According to the simulation that is calibrated by the experimental data, the Baliga’s figure of merits (BFOM) of LCCT-HEMT is around two times higher than that of the conventional UTB-HEMT, hinting at the promising potential of proposed HEMT.
