Does absorption oscillate due to interference?

In UV-VIS analysis of a thin film, suppose we measure Reflectance and absorbance. Absorbance sometimes can be different in meaning. Some instruments include the reflectance in the absorbance, and...

Any suggestions of references for transient photocurrent (like TOF) in amorphous semiconductors with uniform absorption?

I am dealing with amorphous semiconductor films (thickness of the orders of 1-2 microns). A true TOF experiment (where the pulsed light creates a thin sheet of e-h pairs) is difficult because the...

Can anyone suggest a good book on the conduction mechanism in insulators/semiconductors?

I am searching for a text book with theoretical derivations of different types of conduction mechanism in insulators like Schottky emission, thermionic emission, poole-frenkel emission, Hopping...

Do UV-VIS spectrometers take care of reflectance?

Trying to obtain absorption coefficient from absorbance data. (HP 8453 Spectrometer). When a UV-VIS spectrometer measures absorbance as A = log10(I0/I) how does it determine that the loss in the...

How do holes recombine with electrons in single carrier type steady state conduction?

Suppose that e-h pairs are generated on anode surface of an insulator by surface absorption of light. some of the electrons recombine there in surface very shortly. The remaining electrons are...
