A pseudomorphic high-electron mobility transistor (pHEMT) technology for highly integrated wireless components is presented. The technology utilizes 0.5-/spl mu/m gate length, double recess enhancement- and depletion-mode GaAs/AlGaAs/InGaAs transistors. The nominal E-mode pinch-off voltage is +350 mV with IMAX and IDSS of 290 and 0.0005 mA/mm, respectively,(More)
The oxygen reduction reaction is one of the most important chemical processes in energy converting systems and living organisms. Mediator-less, direct electro-catalytic reduction of oxygen to water was achieved on spectrographite electrodes modified by physical adsorption of bilirubin oxidases from Myrothecium verrucaria. The existence of an alternative(More)
