What about the advance in x-ray free electron laser applications ?

European XFEL is constructed such that the electrons produce x-ray light in synchronisation, resulting in high-intensity x-ray pulses with the properties of laser light and at intensities much...

What is the best technique (TEM or SEM) to characterize ISO and ITO films on an SiO2 substrate?

The two techniques give spectra and follow the surface compound. Analytical results had been visible with TEM with EDS, but SEM gave the only image surface with best accuracy.

How can you explain the additive effect on tin oxide to be more sensitive to pollutant gas detection?

Tin oxide SnO2 is used to detect pollutant gas due to its properties of being twice in configuration Sn4+ and Sn2+. But what is amazing is that it is more active when we add additives to it such...

How can I theoretically explain that Ar+ions bombardment form nanostructures on III-V SC surfaces?

The bombardment of the surface of III-V semiconductors lead to the formation of nanostructures on their surfaces Experimentally, at low energy (300 eV) one can obtain nanodots on InSb, InP or...

Can anyone advise me on a theory explaining the dramatic change in band structure of tin oxide when doped?

Experimental results give rise to many applications as gas sensing and solar cells for tin oxide when it is doped by Sb, Ag and Pt. The band structure and the gap change in value and give this...

¿Are oxygen vacancies in semiconductors capable to change the band gap?

Dear all! Oxygen vacancies do raise negatively the Fermi level by increasing the negative charge in the semiconductor crystal structure. In the case of n-type semiconductors, I wonder if this...

I recently calculated the bandstructure of a material using WIEN2k. While the material is semiconductor, my calculation show metallic. Any advise?

I am working on ferrites materials. I could see gap, but the problem is that the conduction band minimum crossed the Fermi Level.

I think, it's meant the same. A tranparent oxide (--> with a large band gap) is an usually doped semiconductor (n-type).

ITO is indium tin oxide, one of many transparent conducting oxides (TCO). I suspect ISO is the same except people form the abbreviation with the element symbol (Sn) instead of the english name.
