semiconductor and the chosen metal, as illustrated inFig. 4.1C and D. The situation with a p-type semiconductor is complementary to the case illustrated inFig. 4.1A–D, that is, the metal will form a diode with a p-type semiconductor if the metal work function is low enough as compared...
A semiconductor device has at least two different gate electrodes. The two different gate electrodes include a first gate electrode on a first gate insulation layer. The first gate electrode includes a first metal-containing conductive pattern on the first gate insulation layer and a second metal-...

Internal photoemission spectroscopy has been used to determine the band alignment in based metal-oxide-semiconductor structures. The Si/interface conduction- and valence-band offsets were determined to be and , respectively. The energy barrier for electrons at the Al/interface is . The value of the...
23). It is generally known that the CBM of an n-type semiconductor is ~0.2 V more negative than the flat-band potential below the CBM45. Therefore, the CBM of TMOF-10-NH2(I) and TMOF-10-NH2(Br) are estimated to be ~−1.11 V vs. NHE and ~−1.37 V vs. NHE, ...
(TMDs) have attracted increasing attention in recent years due to their unique optical and electronic properties and have found many applications in catalysts, optoelectronics, and bio-imaging1,2,3,4. As the electronic band structure of semiconductor materials is relatively sensitive to the quantum ...
