Is it possible for a p-type semiconducting thin film shows Ohmic behaviour from room temperature to a certain higher temperature (300 K- 324 K)?

In a temperature dependent resistivity curve, if the resistivity of a p-type semiconducting thin film increases from room temperature to a certain higher temperature (300 K- 324 K), after that...

Why the reflectance of thin film remain same with higher doping?

Reflectance of CdO thin film decreases for 0.5, 1.0 and 1.5 mol% doped sample. For 2.0 and 2.5 mol% doped samples, Reflectance of the films slightly increased than 0.5, 1.0 and 1.5 mol% doped...

What are the possible reasons for anomalous behaviour of transmittance with doing concentration?

Transmittance of 1.0, 1.5, 2.0 and 2.5 mol% Cr doped samples are lower than pure CdO film but the decrease of transmittance with doping concentration is anomalous, whereas, for 0.5 mol% sample,...

Possible discussion of carrier mobility for Cr doped CdO thin films?

The carrier mobility of the CdO film decreases first, reaching a minimum at 0.5 mol.% Cr doping and then increases with the 1.0, 1.5, 2.0 and 2.5 mol% Cr-doping concentration. What should be the...
