WebAssumptions The beam is long and thin (i.e. L >> h) The beam cross-section is symmetrical with respect to a longitudinal plane (x-y plane); this plane is called the plane of bending. Material obeys the Hooke’s Law. The deformation of the beam is small, linear and elastic. WebIn addition, density functional theory (DFT) calculations suggest that the defect containing one Mo and two S vacancies is the dominant defect inducing the RTFM in MoS2. These DFT results are consistent with Raman, X-ray photoelectron spectroscopy, and ESR spectroscopy results, and they confirm the breakage of Mo and S bonds and the existence of vacancies …
