defining the 3D electron density

Hi,

In the reference cited, Nanowire uses the NEGF formalism and the 3D density is expressed in terms of that formalism. Could someone tell me what the equation will be like in terms of wavefunctions? I do not think it is very different from the reference but I would like to see what the exact form is like if one decide not to use NEGF formalism.

Thanks, George

Saumitra Raj Mehrotra@ onHello,

Ne3D=Sum over mode m(Ne1D.{psi_m.psi*_m)

A more correct representation should be (code being updated), Ne3D=Sum over mode m over mode n

Refer:http://www.iis.ee.ethz.ch/~schenk/JApplPhys_100_043713.pdf

I have written nth mode here which can be understood as nth subband.

I hope it helps

thank, Saumitra
