Electron eigen states in quantum dots revealed by temperature derivative capacitance spectroscopy
Paper in proceeding, 2010
A novel method is presented for detecting confined energy states of quantum dots embedded in junction space charge regions. By determining the temperature derivative of junction capacitance as a function of bias voltage and temperature, spectra are obtained with peaks revealing the existence of electron states. To confirm the reliability of the method, experimental data are compared with the admittance based methods and theory used earlier for interpretation of experimental data. ©2010 IEEE.
