Yes, it is possible for a double perovskite to have an electron mobility of 44cm2/Vs. However, this value can vary depending on the type of double perovskite material and its structure.
The electron mobility of a double perovskite material depends on factors like the chemical composition, crystal structure, grain size, and type of defects. Certain combinations of these parameters can influence the resulting electron mobility. For instance, a double perovskite with larger grain sizes or with fewer types of defects is likely to have a higher electron mobility than one with smaller grain sizes or more types of defects.
Yes, it is possible for a double perovskite material to have an electron mobility of 44 cm²/Vs. Electron mobility is a measure of how easily electrons can move through a material in response to an electric field.
While there is no specific universal value for the electron mobility of all double perovskite materials, it is certainly possible for a specific compound or composition to exhibit an electron mobility of 44 cm²/Vs or even higher, depending on the specific characteristics of the material and the measurement conditions. Experimental studies and theoretical calculations can help determine the electron mobility of a particular double perovskite compound.
