Well FTIR spectrometers have a infrared source(IR), has a broad spectrum, first goes to the beam splitter then 50% is reflected and transmitted. The reflected beam is reflected back by the fix mirror and the transmitted beam is reflected by the moving mirror to the beam splitter. Two beams...

Many thanks!

I was suppose to say Analog multipliers.

I need to get information about multiplier circuits. Thanks,

Well materials have valance and conduction bands. The distance between the valance and conduction band is defined as band gap. As the band gap get bigger materials become more insulator because it gets harder for to excite an electron from the valence band into the conduction band. There is...

Are you using FTIR spectrometer? if not can you give little information about the lab setup to have better understanding?

1)-The relationship between Vt and the channel length is called short channel effect. If you search on the web you can find enough information. The third term in your equation needs a modification to see the relation between Vt and L. 2)- Cox's units can be modified depend on the units of the...

Hello, I'm trying to model a optic sytem, includes a IR light source, FTIR spectrometer, and lock-in amplifier. I wonder if anyone has knowledge about any tutorials for designing such a system. Thanks

Thanks

Hi I need help on a project of graphene photo detector by using FTIR spectrometer but I'm not sure how to set up equipments. I wonder if someone can help me. Thanks
