What is the effect on capacitance of inter-digitated capacitor (IDC) with frequency?

Capacitance of IDC depends on the dielectric material used in IDC. I think, capacitance is decreased with increasing frequency because at high frequency dielectric don't hold the charge so charge...

What is basic difference between Quantum dots and nanoparticles? What is exact size of these?

I think that all quantum dots are nanoparticles but it is not true that all nanoparticles are Quantum dots. I think quantum dots having size 2nm- 10nm diameter and nano particle having size about...

What is an effect of capping ligand on the surface of QDs (cdse,cds) in their optical properties decay time,PL intensity, etc?

I think decay time of QDs, is increase and PL is also increase.

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.
