Pulse transient method used for analysis of temperature modulated space charge limited currents

Original language description

Space charge limited currents (SCLC) plays a key role in studies of the localised energy states distribution into a forbidden energy band gap of inorganic and/or organic semiconductors. The shape (slope) of the current-voltage characteristics reflect theamount of trapped electrons (holes) injected into the semiconductor on the change of the Fermi energy level [1, 2]. Utilising the temperature modulated space charge limited current (TM SCLC) characteristics it began to be possible to determine the energetic position of the states responsible for the electron (hole) trapping [3, 4, 5]. The method was used as a semistationary: the measurement was performed as a slow temperature wobbling near the room temperature. However, the method fails when the activation energies are low (~kT) because the experimental error of the steepness determination from the Arrhenius dependence of electric current (ln I = f(1/T)) significantly increases in this region. In this contribution, we present a modific
