    摘要： Disclosed are a method of making GaAs-based enhancement-type MOS-FETs, and articles (e.g., GaAs-based ICs) that comprise such a MOS-FET. The MOS-FETs are planar devices, without etched recess or epitaxial re-growth, with gate oxide that is primarily Ga2O3, and with low midgap interface state density (e.g., at most 1×1011 cm−2 eV−1 at 20° C.). The method involves ion implantation, implant activation in an As-containing atmosphere, surface reconstruction, and in situ deposition of the gate oxide. In preferred embodiments, no processing step subsequent to gate oxide formation is carried out above 300° C. in air, or above about 700° C. in UHV. The method makes possible fabrication of planar enhancement-type MOS-FETs having excellent characteristics, and also makes possible fabrication of complementary MOS-FETs, as well as ICs comprising MOS-FETs and MES-FETs. The method includes deposition of gate oxide of overall composition GaxAyOz, where Ga substantially is in the 3+ oxidation state, A is one or more electropositive stabilizer element adapted for stabilizing Ga in the 3+ oxidation state, x is greater than or equal to zero, z is selected to satisfy the requirement that both Ga and A are substantially fully oxidized, and y/(x+y) is greater than 0.1.

    摘要： A high quality interface between a GaAs-based semiconductor and a Ga.sub.2 O.sub.3 dielectric an be formed if the semiconductor surface is caused to have less than 1% of a monolayer impurity coverage at completion of the first monolayer of the Ga.sub.2 O.sub.3 on the surface. This is achieved, for instance, by preparing the surface of a GaAs wafer under UHV conditions in a first growth chamber, transferring the wafer through a transfer module under UHV to a second growth chamber that is also under UHV, and growing the dielectric by evaporation of Ga.sub.2 O.sub.3 from a solid source, the process carried out such that the integrated impurity exposure of the surface is at most 100 Langmuirs. Articles according to the invention have low interface state density (

    摘要： Embodiments of the present invention provide binding molecule-functionalized high electron mobility transistors (HEMTs) that can be used to detect toxins, pathogens and other biological materials. In a specific embodiment, an antibody-functionalized HEMT can be used to detect botulinum toxin. The antibody can be anchored to a gold-layered gate area of the HEMT through immobilized thioglycolic acid. Embodiments of the subject detectors can be used in field-deployable electronic biological applications based on AlGaN/GaN HEMTs.
