Is it necessary that the I-V between source and drain should pass from (0,0) at any gate voltage?

I have fabricated MESFET by depositing GeSe thin film on glass substrate and then deposited silver metal for gate. Now when I record I-V between source and drain at 0 gate voltage it passes from...

Is it possible to get direct bandgap greater than indirect bandgap?

I have synthesized Sb incorporated GeSe ternary alloys. The proportion of Sb varies as 10% and 15% by weight proportion. In 15% Sb incorporated GeSe, I am getting direct bandgap to be 0.94eV and...

Why Sb peak is missing in EDS spectra, whereas it is recorded in elemental mapping?

I have recorded EDS spectrum of Sb doped GeSe ternary alloy. Now my problem is, I am not getting any peak for Sb in the spectrum but when elemental mapping is conducted on the sample, a uniform...

Normal trend of Raman peaks is the intensity increases with decrease in temperature. But is the reverse behavior possible?

In temperature dependent Raman studies the general trend of peak intensity w.r.t. temperature is that it decreases and starts broadening with increase in temperature. But in one of my sample I am...

Is photo-bolometric effect possible in TMDC materials at 0 biasing voltage or is observed only when some biasing voltage is applied?

In my TMDC bulk crystal samples I am getting photoresponse in opposite direction i.e. dark current is more than illuminated current. Such type of effect is possible due to either photo-voltaic...

Does the crystallite size always decrease and microstrain always increase irrespective of type of dopant (trivalent or pentavalent) in TMDC crystals?

My host material is a p-type semiconductor and my dopant is an electron donor atom so what result should I expect for crystallite size and microstrain of the doped material from powder xrd of the...
