AbstractThe typical photocurrent decay time τR in intrinsic prepared hydrogenated microcrystalline silicon (μc-Si:H) is around lms similar to its n-doped amorphous counterpart (a-Si:H:P). Depending on the crystalline fraction Xc, the μc-Si:H films show an activation energy near to or below 0.5eV. To find out if this analogy ofτR could be due to a Fermi level shift or to the grainy structure in gc-Si:H films, we have studied the behaviour of τR in doped a-Si:H and gc-Si:H films of different XC. One-dimensional numerical simulation based on the Multiple Trapping Model (MTM) can explain this increase in terms of a Fermi level shift towards the conduction band. On the other hand, detailed measurements for temperatures from 100 to 400 K point to carrier trapping in deep states, most probably located at grain boundaries.

Van Hove Superconductor

To understand the origin of high temperature superconductivity model based on the close proximity of the Fermi level to a quasi-two-dimensional Van Hove Singularity (VHS) in the density of states has been suggested. Here we present our study of the dependence of the zero temperature gap to the critical temperature for s- and d-wave superconductors on the Fermi level shift (δ) from the VHS within the BCS theory. Exact numerical calculations for the s and d gap ratios are carried out and approximate analytic expressions for the ratio are given. We find that the maximum gap ratio occurs at δ=0, and it decreases symmetrically with increasing δ.
