We present a silicon nanowire-based field-effect transistor biosensor with Schottky barriers for highly specific and sensitive human α-thrombin detection. The active sensor area is decorated with thrombin-binding aptamers as receptor molecules. Each sensor chip is integrated into a microfluidic device for flow-through measurements. Instantaneous detection is provided by real-time monitoring of FET...
In this paper, a technology for top-down single-gated Schottky barrier transistor is presented exhibiting the highest symmetry of on-currents for n- and p-conductance of such silicon-on-insulator-based devices. The symmetry in the current-voltage-characteristics is a mandatory requirement to realize circuits with reconfigurable nanowire field effect transistors (RFETs) whose channel can be switched...
Reconfigurable fine-grain electronics target an increase in the number of integrated logic functions per chip by enhancing the functionality at the device level and by implementing a compact and technologically simple hardware platform. Here we study a promising realization approach by employing reconfigurable nanowire transistors (RFETs) as the multifunctional building-blocks to be integrated therein...
Reconfigurable Nanowire Transistors merge the electrical properties of unipolar n- and p- type FETs into a single type of device with identic technology, geometry and composition. These four-terminal nanowire transistors employ an electric signal to dynamically program unipolar n- or p-type behavior. More than reducing the technological complexity, they open up the possibility of dynamically programming...
Nanoscale electronic devices have the potential to achieve exquisite sensitivity as sensors for the direct detection of molecular interactions, thereby decreasing diagnostics costs and enabling previously impossible sensing in disparate field environments. Semiconducting nanowire-field effect transistors (NW-FETs) hold particular promise, though contemporary NW approaches are inadequate for realistic...
