Quantum Mechanical Aspects of Transport in Nanoelectronics

Innovations in semiconductor technology have provided us with an opportunity to examine devices with vertical and lateral dimensions less than 100 nm-comparable to the wavelength of the electron at the Fermi energy. At low temperature, the confinement and the coherence of the electronic motion on the scale of the electron wavelength give rise to gross deviations from classical charge transport ...

Oxide nanoelectronics on demand.

Electronic confinement at nanoscale dimensions remains a central means of science and technology. We demonstrate nanoscale lateral confinement of a quasi-two-dimensional electron gas at a lanthanum aluminate-strontium titanate interface. Control of this confinement using an atomic force microscope lithography technique enabled us to create tunnel junctions and field-effect transistors with char...

Atomic scale nanoelectronics for quantum neuromorphic devices: comparing different materials

I review the advancements of atomic scale nanoelectronics towards quantum neuromorphics. First, I summarize the key properties of elementary combinations of few neurons, namely long– and short–term plasticity, spiketiming dependent plasticity (associative plasticity), quantumness and stochastic effects, and their potential computational employment. Next, I review several atomic scale device tec...

Revisiting focus prosody in Japanese*

This paper revisits Japanese focus prosody by comparing the realization of contrastive focus vs. neutral focus across 4 focus positions and 2 accenthoods. Post-focus F0 Range compression (PFC) is found only in accented stimuli, while focus in unaccented stimuli is marked by Min F0 lowering. Penultimate focus differs from other focus positions, in terms of its post-focus behavior. Intensity and ...
