SRH recomb.

[Dipankar Saha]

Hi,
Can we emulate the effect of SRH recomb. ??!  If yes... then, how can we?

Thanks _

Hi Dipankar. What do you mean "SRH recomb." ?

[Dipankar Saha]

Hiii Jess.....

I was just looking for some entity which may give the estimation of the 'inter layer recombination'  (may not be exactly the same, but somewhat a similar effect what we call SRH recomb. , i.e. R ~ n1 * p2  / t(n1 + p2) ; where 'n1' and 'p2' are carrier densities of the two materials forming vdW struct. and 't' is the recomb. life time) ...

The SRH recombination is trap-assisted recombination, so that there will be no SRH recombination in layered semiconductor materials if there are no defect levels in the mid-gap of the semiconductor. So, you first need to identify what is the recombination mechanism in your system to figure out the actual 'entity' that might be calculated from ground state DFT to be then used for the recombination problem.

Petr Khomyakov,

 I understand your point..... / Thank you....
