Mott-schottky curve
Nettet12. des. 2024 · The donor density (ND) in a Mott Schottky curve can be calculated by fitting the measurement data to a theoretical model of the diode. In particular, the value of ND is directly related to the capacitance charge of the diode at a given voltage, which can be derived from the data by measuring the slope of the Mott Schottky curve. Nettet23. apr. 2024 · In this work, CZTS particles with a mixed phase of wurtzite and kesterite were synthesized by the solvothermal method. The time-dependent XRD patterns, Raman spectra, SEM, and EDS analysis were employed to study the growth mechanism of CZTS. The results revealed that the formation of CZTS started from the nucleation of …
