We report the first observation of five water trimer isotopomers using terahertz laser spectroscopy coupled with a pulsed slit jet expansion technique. A single c-type vibration-rotation-tunneling (VRT) band has been observed for each isotopomer between 40 and 50 cm-1. By considering all the experimental data, including results from isotopic substitution experiments, analyses of bifurcation tun...

The foundational Franz-Keldysh effect and Einstein model are applied in this work to characterize semiconductor band-edge absorption---and its departures from ideality. We unify the models fully field-induced tunneling of photoexcited electrons degenerate valence bands into conduction band, with encroachment band gap arising as an Urbach tail. Our unified is implemented for semi-insulating indi...

We study interlayer transport in double-layered (mmm) quantum Hall liquids in the weak tunneling limit, in particular the effects of lead geometry on the I-V characteristics of interlayer tunneling. We proposed several practical ways to study experimentally the novel interlayer transport properties in the double-layered (mmm) quantum Hall liquids. Some concrete predictions on the DC characteris...

We report the energy level alignment evolution of valence and conduction bands of armchair-oriented graphene nanoribbons (aGNR) as their band gap shrinks with increasing width. We use 4,4″-dibromo-para-terphenyl as the molecular precursor on Au(111) to form extended poly-para-phenylene nanowires, which can subsequently be fused sideways to form atomically precise aGNRs of varying widths. We mea...

two different methods of bayesian segmentation algorithm were used with different band combinations. sequential maximum a posteriori (smap) is a bayesian image segmentation algorithm which unlike the traditional maximum likelihood (ml) classification attempts to improve accuracy by taking contextual information into account, rather than classifying pixels separately. landsat 7 etm+ data with pa...

The Tunneling-Dielectric TFT (TDTFT), that has thin dielectric films at both ends of the channel fabrication area, was fabricated with 1.7 nm SiNX film by LPCVD method. The conduction mechanism of the drain currents was examined in the temperatures from 293 to 623 K experimentally and theoretically. The Id-Vg characteristics were reproduced by the direct tunneling (DT) via SiNX film with an ass...

a fourth-degree substrate integrated waveguide (siw) crossed coupled band pass filter for wlan band is designed by using a new negative coupling structure. it consists of two u shape microstrip lines on top and bottom planes with via holes at the center of them. this paper investigates the phase characteristics of negative and positive coupling structures and their effects. the design, fabricat...

A prerequisite for future graphene nanoribbon (GNR) applications is the ability to fine-tune the electronic band gap of GNRs. Such control requires the development of fabrication tools capable of precisely controlling width and edge geometry of GNRs at the atomic scale. Here we report a technique for modifying GNR band gaps via covalent self-assembly of a new species of molecular precursors tha...

In this letter we present a simple relation, that allows one to predict the Josephson current between two unconventional superconductors with arbitrary band-structure and pairing symmetry. We illustrate this relation with examples of s-wave and d-wave junctions and show a detailed numerical comparison with the phenomenological Sigrist and Rice relation [1] commonly used to interpret tunneling e...
