The temperature dependence of the thermal expansion of KI and RbI at high temperatures is shown to be related to the concentration of thermally generated Schottky defects. the experimental value of the energy of formation of these defects for RbI has been estimated for the first time. The two ...
It is shown that the experimental current鈥搗oltage characteristics are in agreement with a simple physical model that takes into account the thinning of the Schottky barrier due to the space charge of ionized deep centers, which stimulates the concentration of the electric field near the Schottky...
This is an important implication for the charge and potential distribution at the semiconductor/electrolyte interface. The Mott Schottky analysis hasshown that the present materials are n-type semiconductors with donor defect concentration of 7.4x10 17 /cm 3 . DOI: http://dx.doi.org/10.3126/jncs...
The band diagram of a Schottky barrier on a p-type semiconductor is shown in Figs. 3(a) and 3(b) before and after making contact, respectively. The depletion layer contains negatively-charged ionized acceptors, compensated by a positive surface charge on the metal. The built-in voltage is ...
Schematics of FP structure is shown in Figure 3b. Bandić et al. first compared GaN lateral SBD with a field plate on sputtered SiO2 dielectric layer and without field plate and found the field plate can sup- press the leakage current by one to two orders of magnitude. Simulation was ...
f, The extracted p-type Schottky barrier height at various gate voltages, where the flat-band hole Schottky barrier is measured to be 67 mV. The flat-band voltage and corresponding Schottky barrier are shown by the dashed lines. Tran, transferred. Extended Data Fig. 5 Highest-electron-...
GaN epitaxially grown on Si is a material for power electronics that intrinsically shows a high density of dislocations. We show by Conductive Atomic Force Microscopy (C-AFM) and Defect Selective Etching that even for materials with similar total disloca
at the interface of semiconductor heterojunctions, a rapid recombination of accumulated electrons and holes often transpires within a short interval, thus affecting the establishment of interfacial BIEF [30,31]. Fortunately, investigations have shown that Mott–Schottky heterojunctions established through in...
