  • Abstract
    The hole multiplication factor in pnp In0.52Al0.48 As/In0.53Ga0.47As single heterojunction bipolar transistors (HBTs) has been measured as a function of the base-collector bias. The hole impact ionization coefficient βp has been estimated by taking into account the Early effect, the collector-base leakage current ICBO, thermal effects and the spread in the nominal device processing parameters. Numerical corrections for dead space and current-induced collector charge density variations were made. The data obtained in this way agree with the most recent photomultiplication measurements available in literature
