This work describes the improved uniformity of short gate length (sub100nm) T-gate lithography observed for InP HEMT devices through the development of a nonannealed ohmic contact process. The incorporation of such a process allows the reversal of ohmic and gate levels as part of a standard device process flow. This eliminates fluctuations in the gate(More)
An InGaAs/InAlAs based HEMT structure, lattice matched to an InP substrate, is presented in which drive current and transconductance has been optimized through a double-delta doping strategy. Together with an increase in channel carrier density, this allows the use of a non-annealed ohmic contact process. HEMT devices with 120 nm standard and self-aligned(More)

The proteinases from Carica papaya include papain, isoenzymes of chymopapain and two proteinases A and B distinguished by their unusually high pI. The identity of one of the most basic proteinases has been questioned. The present report describes the preparation and characterisation of two monoclonal antibodies that react specifically with papaya(More)
As part of a study designed to reveal information about molecular features of allergenic food proteins after absorption from the gut the specificity of antibodies in normal human serum to hen's egg ovalbumin was investigated using ELISA techniques. Preliminary investigations with monoclonal antibodies and hyperimmune rabbit antiserum specific for ovalbumin(More)
