I am trying to simulate a Silicon Heterojunction (SHJ) Solar Cell in Silvaco. How do I model the charge transport at ITO/a-Si(p) interface?

The ITO(n)/a-Si(p) interface creates an opposing diode for the c-Si(n) based SHJ.I am trying to implement hole tunnelling using bbt.nonlocal and tat.nonlocal models.No matter how small the qtmesh...

At the surface of a semiconductor (say Silicon), what is the origin of donor-like and acceptor-like states?

I understand that there is a presence of surface defects due to presence of dangling bonds. A Silicon atom at the surface will not have a nearest neighbour to bond with and it will have a space...

Why is the threshold voltage of MOS capacitor not equal to the voltage corresponding to Cmin?

In the image, threshold voltage (Vt) lies at point 4 which is a point where weak inversion has just started, why is Vt located there and not at the point of Cmin? Why is the weak inversion region...
