  • Patent number: 9316637
    Abstract: Embodiments of the invention include sensors comprising high electron mobility transistors (HEMTs) with capture reagents on a gate region of the HEMTs. Example sensors include HEMTs with a thin gold layer on the gate region and bound antibodies; a thin gold layer on the gate region and chelating agents; a non-native gate dielectric on the gate region; and nanorods of a non-native dielectric with an immobilized enzyme on the gate region. Embodiments including antibodies or enzymes can have the antibodies or enzymes bound to the Au-gate via a binding group. Other embodiments of the invention are methods of using the sensors for detecting breast cancer, prostate cancer, kidney injury, glucose, metals or pH where a signal is generated by the HEMT when a solution is contacted with the sensor. The solution can be blood, saliva, urine, breath condensate, or any solution suspected of containing any specific analyte for the sensor.

  • Patent number: 9236443
    Abstract: High electron mobility transistors (HEMTs) having improved I-V characteristics and reliability are provided. According to one embodiment, a selective implantation is performed to form a damage region in a gate-to-drain region of, for example, an I?A?N/GaN HEMT. The selective implantation can be performed by irradiating some or all of a gate-to-drain region of an InAlN/GaN HEMT on a substrate with protons or other ions such as Ge ions, He ions, N ions, or O ions. The damage region can extend in a region below a 2DEG interface of the HEMT.

  • Publication number: 20140339700
    Abstract: Contacts for semiconductor devices are formed where a barrier layer comprising graphene is situated between a first layer comprising a conductor, and a second layer comprising a second conductor or a semiconductor. For example, a metal layer can be formed on a graphene layer residing on a semiconductor. The barrier layer can be directly formed on some second layers, for example, graphene can be transferred from an organic polymer/graphene bilayer structure and the organic polymer removed and replaced with a metal or other conductor that comprises the first layer of the contact. The bilayer can be formed by CVD deposition on a metallic second layer, or the graphene can be formed on a template layer, for example, a metal layer, and bound by a binding layer comprising an organic polymer to form an organic polymer/graphene/metal trilayer structure. The template layer can be removed to yield the bilayer structure.

  • Patent number: 8578757
    Abstract: Exemplary embodiments provide a self-powered wireless gas sensor system and a method for gas sensing using the system. The system can be used to detect and constantly track a presence of various gases including hydrogen, ozone and/or any hydrocarbon gas, and remotely transmit the sensing signal. The system can include a low power gas sensor that consumes less than about 30 nano-watts of power. As a result, the system can detect the presence of hydrogen at about 10 ppm. The sensor can also provide a fast response time of about 1-2 seconds. In various embodiments, the system can be physically small and packaged with all components assembled as a single compact unit.
