Abstract

We have previously shown from static planar conductance measurements that a strong inversion layer does exist in c-Si at the (n) a-Si:H/ (p) c-Si interface. This allowed us to determine the conduction band offset with a good precision (ΔE_C = 0.15 +/- 0.04 eV). The same technique is now applied to study (p) a-Si:H/ (n) c-Si interfaces. We demonstrate that a strong inversion layer (of holes) also exists at the c-Si surface of this hetero-interface. Analysis of our planar conductance data with the help of numerical simulations allows us to set a lower limit to the valence band offset, ΔE_V = E_V,a-Si:H - E_{V, c-Si} : ΔE_V> 0.28 eV.
