Study of electrical and dielectric properties of perovskites
 Moravčík, Marek ; Pospíšil, Jan (referee) ; Zmeškal, Oldřich (advisor)
This bachelor’s thesis is focused on a study of electrical and dielectrically properties of perovskite single crystal prepared by inversed temperature crystallization. Measurement was done on sample of MAPbBr3. First the temperature dependences of current-voltage characteristics were measured, they help to determined Arrhenius dependences. Activation energies were determined from Arrhenius dependences for every single voltage. These activation energies were used to determined position of Fermi level during thermodynamic balance. Concentration of state for dominant energies and charge carrier mobility (drift, microscopic) were determined from current-voltage characteristics for constant temperature. Relative permittivity was used to determine these parameters from impedance measurement.
