Set up of electrochemical set to characterize BG of semiconductors?

11 November 2017 1 2K Report

We need suitable refrences for Set-up and electrochemical test standards for measuring the semiconductor gap band, could you please guide us?

Anne Davidson

It depends, which BG do you want to measure:

in UV I will recommend a commercial titania (Degussa P25 or an other)

in the visible, you can try hematite which BG is around 2.2 eV for bulk cristals,

in the NIR any lanthanide dopant can be helpful.

Does this answer help you?

How the Ground Plane implantation is performed without damaging (and w/o varying the undoped nature) the top Si (8-10 nm) in FDSOI technology ?

It is a general practice to introduce Ground Plane in FDSOI devices under the BoX. The Ground Planes are introduced by Ion Implantation through Top Si layer and Buried Oxide. I wanted to know that...

Can a semi-conductor material have different absorption coefficient?

Does the absorption coefficient of the semiconductor changes with the change in the structure of the semiconductor? If you have a thin film and nanowire of the same semiconductor, will the...

Is there an ideal incubation time of RGO-modified SPCE before subsequent use, i.e., electrochemical characterization or further modification?

I notice that upon washing and air-drying of my RGO/SPCE surface and characterizing again via DPV, the current response towards ferricyanide probe significantly decreases. My worry is that the...

How can we determine the band gap of a composite material that is made up of a composition of direct and indirect band gap semiconductor materials?

I have a direct band gap material and an indirect band gap material. If I made a composite of both through physical mixing. Then how can I determine the band gap of such a material as the Tauc...

Despite single-cell RNA, how can I characterize a new cell subtype/phenotype?

A new cell subtype was found out only during regeneration phases after a cuprizone-induced demyelination model. How can I characterize this cell? It is important to highlight that was already...

How can I spin a thick layer of organic polymer?

I need to spin a 120um thick film. My current procedure consists of spinning the polymer (about 20um), uv exposure, plasma etch, and then spinning another 20um thick layer, uv again, plasma etch...
