Development and Characterisation of a Radiation Hard Readout Chip for the LHCb-Experiment

Daniel Baumeister
At the grain boundaries, a bending of the energy band is present [Wag92] which results in a potential barrier limiting the current flow.  ...  In poly-crystalline silicon the current flow beyond the grain boundaries is determined by the bending of the energy bands and unaffected by lattice defects.  ...  This is due to an error in the tristate buffers inside the control circuit.  ...
