I wanted to study electrical behavior of thin films. Can anybody suggest me suitable source measure unit please?
(also of low budget)
Power supply: Voltage (few volts)
measurement: current (micro- milliamps)
However, all ten thousand (s) of crystalline materials fall into 230 space groups only. out of that, many systems have peaks near 32 degrees. Very less number of systems have peak in the range of 20-30.
I should not have used 'almost every'.
Thanks for the reply. Still I doubt whether electrons are ejected out from the atoms of sample or not during the xrd. Since energy of the Cu Kα photons is huge compared to Al kα photon,it seems electrons seems to be get ejected, however it is not observed and mentioned anywhere. Please help me...
Thanks for clearing my earlier doubt.
Why can't Cu K alpha eject electrons from atoms of the sample in XRD?
As everyone knows, Al K alpha photon with 1486 eV energy is used for XPS to remove electrons from core levels. My doubt is why cant Cu K alpha photon with 8000+ eV do that?
I wanted to know how to find out absorption coefficient (alpha) of a uv-vis spectrum of thin film to determine energy gap of he material. Somewhere (http://www.sciencedirect.com/science/article/pii/S0925346709003656) it is written like if you know thickness then we can find out alpha. Is it...
