Time resolved electro-optical admittance measurements were performed on mono-crystalline Rutile thin films through an optically transparent rolled-up gold gate. Excitation pulses of different wavelengths in the infrared band were applied to the structure as a function of the temperature and the electric field and the admittance transients were recorded. The analysis of the time evolution reveals a binding energy of 0.6 eV for a single prominent defect level. Furthermore, a temperature and light intensity dependent delayed trap response was observed and investigated under various conditions.
