Abstract: | In this thesis, the effective Hamiltonian of a monolayer WS2 in an electric field will be analyzed in order to get information about enhancing the energy band gap of the monolayer WS2. After applying an external perpendicular magnetic field, the effective Hamiltonian of the WS2 monolayer will be studied in the case of absence and presence of Zeeman term. The electronic properties such as the energy gap and the band structure of the monolayer in the presence of electric and magnetic fields will be considered. Using the utilized information other properties such as the density of states, and Fermi energy will be discussed at different strengths of magnetic fields and temperatures. The added magnetic field will alter the electronic spectra and the Landau levels of the monolayer WS2 will appear. Using the partition function the average energy, specific heat capacity, the magnetization and magnetic susceptibility will be considered in the presence and absence of Zeeman term. The effect of increasing the band gap by increasing the applied electric field will be considered on electronic, thermal and magnetic properties for the K valley and K′ valley of the WS2 monolayer. |
