PHOTOEMISSION STUDY OF METALS AND SEMICONDUCTORS BY USING A SPATIALLY VARYING VECTOR POTENTIAL

2024-06-19T05:50:13Z

Title: PHOTOEMISSION STUDY OF METALS AND SEMICONDUCTORS BY USING A SPATIALLY VARYING VECTOR POTENTIAL Authors: Gurung, Shivraj Abstract: The kronig-penney potential is used to define the crystal potential from which the wave function for the surface state is derived. The wave function thus obtained is used for photoemission calculations in the case of transition metals like W and Ni and semiconductors like lead salt using a spatially dependent vector potential. PACS: 79.60-i, 61.80Ba, 78.68+m, 41.20Jb

Photocurrent calculations in semiconductors using Kronig-Penney model

2024-06-19T05:29:31Z

Title: Photocurrent calculations in semiconductors using Kronig-Penney model Authors: Gurung, Shivraj Abstract: Photoemission calculations have been done usjng the Kronig-Penney model from band state (Fermi level) of semiconductors silicon and gallium arsenide. For the evaluation of pilotocurrent the initial state wavefunction u.sed is tlie one deduced by lhapa and Kar PureAppl. Phys. 26 620(1988)] [1].
