Superlattice-source nanowire FET with steep Subthreshold characteristics
… mV/dec subthreshold swing of a conventional MOSFET is a fundamental limit to the continuation of transistor power scaling. In order to further reduce transistor power consumption and transistor footprint, new subthreshold transport mechanisms other than thermionic emission over an energy barrier …

The metaphysical and poetical universe of A. A. Fet
"The previously-neglected metaphysical aspect of Fet's poetry discussed in this thesis mainly concerns itself with the philosophical, ontological and aesthetical basis of his lyrics. Fet's Memoirs (1890) and correspondence with friends, such as L. Tolstoi, Iakov Polonskii, and I. Turgenev, his …

Electrostatic control of microfluidic systems for enhancement of nanoparticle separations and FET nanobiosensors
… Biosensors based on the field-effect transistor (FET) are capable of detecting molecular binding or hybridization events through direct coupling of analyte charge with conduction through the FET. This label-free approach can be used to realize ultraportable and point-of-care (POC) diagnostic …
