n = 4. A further examination of the local minima for (LizI)+-. (CH,0H)4 reveals another structure which, although much less. 'stable, is of considerable interest (Figure 7). All the methano1 molecules have grouped around one end of the alkali halide

Jun 28, 2016 - This means that the breakdown that occurred within this small voltage region is a Zener breakdown because the breakdown originating from Zener tunneling has a ... This broadband spectral response of the WS2/Si photodiode is similar to

52 mins ago - An emerging class of semiconductor heterostructures involves stacking discrete monolayers such as the transition metal dichalcogenides (TMDs) to form van der Waals heterostructures. In these structures, it is possible to create interlay

Mar 22, 2017 - The high figure-of-merit UV detectivity D* in exceeding 1 × 1014 Jones represents more than 1 order of magnitude improvement over the best reported previously on ZnO nanostructure-based UV detectors. This result not only sheds light o

May 4, 2018 - In these structures, it is possible to create interlayer excitons (ILEs), spatially indirect, bound electron–hole pairs with the electron in one TMD ...

Jun 28, 2016 - The WS2/Si heterojunction working in the Zener breakdown regime shows a stable and linear photoresponse, a broadband photoresponse ranging from 340 to 1100 nm with a maximum photoresponsivity of 5.7 A/W at 660 nm and a fast response sp
