In this study, we examine the effects of a Hubbard corrected energy functional on the lattice thermal conductivity of wurtzite ZnO calculated using density functional theory and an iterative solution to the Boltzmann transport equation.
WitrynaTemperature causes an increase in conductivity. Between 1.5 and 5.0% per °C, this rise is substantial. Therefore, unless a temperature correction is applied, the conductivity of the same solution measured at different temperatures will vary. Because of this, conductivity data need to be temperature adjusted. Witryna29 wrz 2024 · Calibrating Conductivity meters is important to ensure their abilities to measure how well solutions conduct electricity and remain accurate. You should calibrate the instrument each time it is used in order to get accurate readings at all times. Calibration of these meters require the use of a solution that has a known …
