Carbon-Nanotube/$\beta$-Ga$_2$O$_3$ Heterojunction PIN Diodes
[ "Ellis Hunter D. ", "Li Botong ", "Xie Haoyu ", "Fan Jichao ", "Rahaman Imteaz ", "Gao Weilu ", "Fu Kai " ]
$\beta$-Ga$_2$O$_3$ is gaining attention as a promising semiconductor for next-generation high-power, high-efficiency, and high-temperature electronic devices, thanks to its exceptional material properties. However, challenges such as the lack of viable p-type doping have hindered its full potential, particularly in ...

Structural stability, elemental ordering, and transport properties of layered ScTaN2
[ "Julien Baptiste ", "Leahy Ian A. ", "Smaha Rebecca W. ", "Mangum John S. ", "Perkins Craig L. ", "Bauers Sage R. ", "Zakutayev Andriy " ]
Some ternary TM nitrides are predicted to adopt layered structures that make them interesting for thermoelectric conversion and quantum materials applications. Synthesis of TM ternary nitride films by physical vapor deposition often favors disordered 3D structures rather than the predicted 2D-like layered structure. ...

Effects of Boron Purity, Mg Stoichiometry and Carbon Substitution on Properties of Polycrystalline MgB$_{2}$
[ "Ribeiro R. A. ", "Bud'ko S. L. ", "Petrovic C. ", "Canfield P. C. " ]
By synthesizing MgB$_{2}$ using boron of different nominal purity we found values of the residual resistivity ratio ($RRR = R(300 K) / R(42 K)$) from 4 to 20, which covers almost all values found in literature. To obtain high values of $RRR$, high purity reagents are necessary. With the isotopically pure boron we obt...

Crossovers Between Elastic, Plastic and Quantum Creep in Two Dimensional YBa_2Cu_3O_7/PrBa_2Cu_3O_7 Superlattices
[ "Qiu X. G. ", "Moshchalkov V. V. ", "Bruynseraede Y. ", "Jakob G. ", "Adrian H. " ]
Two-dimensional(2D) vortex dynamics was studied in an YBa_2Cu_3O_7/ PrBa_2Cu_3O_7 superlattice by measuring the I-V characteristics. In the high current limit, 2D collective creep was observed with an activation energy characterized by U(j)=a j^u. A dislocation mediated vortex melting happened when the temperature in...

[ "Gaevski M. E. ", "Bobyl A. V. ", "Shantsev D. V. ", "Galperin Y. M. ", "Tret'yakov V. V. ", "Johansen T. H. ", "Suris R. A. " ]
Spatially-resolved studies of a YBaCuO thin film bridge using electron probe microanalysis (EPMA), low-temperature scanning electron microscopy (LTSEM), and magneto-optical flux visualization (MO) have been carried out. Variations in chemical composition along the bridge were measured by EPMA with 3 microns resolutio...

Low energy excitations in crystalline perovskite oxides: Evidence from noise experiments
[ "Ghosh Arindam Indian Institute of Science, Bangalore, India", "Raychaudhuri A. K. ", "Sreekala R. ", "Rajeswari M. ", "Venkatesan T. " ]
In this paper we report measurements of 1/f noise in a crystalline metallic oxide with perovskite structure down to 4.2K. The results show existence of localized excitations with average activation energy $\approx$ 70-80 meV which produce peak in the noise at T $\approx$ 35-40K. In addition, it shows clear evidence o...

Unusual features in the nonlinear microwave surface impedance of Y-Ba-Cu-O thin films
[ "Kharel A. P. ", "Velichko Anton V. ", "Powell J. R. ", "Porch A. ", "Lancaster M. J. ", "Humphreys R. G. " ]
Striking features have been found in the nonlinear microwave (8 GHz) surface impedance $Z_s=R_s + jX_s$ of high-quality YBaCuO thin films with comparable low power characteristics [$R_{res}\sim 35--60 \mu\Omega$ and $\lambda_L(15 K)\sim 130--260 nm$]. The surface resistance $R_s$ is found to increase, decrease, or re...

Stacks of a few intrinsic tunnel junctions were micro-fabricated on the surface of Bi-2212 single crystals. The number of junctions in a stack was tailored by progressively increasing the height of the stack by ion-beam etching, while its tunneling characteristics were measured in-situ in a vacuum chamber for tempera...

Change in the adiabatic invariant in a nonlinear two-mode model of Feshbach resonance passage
[ "Itin A. P. ", "Vasiliev A. A. ", "Watanabe S. ", "Krishna G. " ]
Mean-field approach has recently been used to model coupled atom-molecular Bose-Einstein condensates (BEC) and coupled Fermi-Bose condensates near Feshbach resonance. Sweeping of magnetic field across the resonance gives a new (nonlinear) version of Landau-Zener problem. We investigate the structure of the correspond...

Carnot cycle for an oscillator
[ "Arnaud J. ", "Chusseau L. ", "Philippe F. " ]
Carnot established in 1824 that the efficiency of cyclic engines operating between a hot bath at absolute temperature $T_{hot}$ and a bath at a lower temperature $T_{cold}$ cannot exceed $1-T_{cold}/T_{hot}$. We show that linear oscillators alternately in contact with hot and cold baths obey this principle in the qua...

A dynamical instability of the Fermi sea against association into molecules initiates the c...
