Ultrafast responses of BCS superconductor Nb(1-x)Ti(x)N films in a nonadiabatic excitation regime were investigated by using terahertz (THz) pump-THz probe spectroscopy. After an instantaneous with the monocycle THz pump pulse, transient oscillation emerges electromagnetic response gap energy region. The frequency coincides asymptotic value energy, indicating appearance theoretically anticipated collective amplitude mode order parameter, namely Higgs mode. Our result opens new pathway to...
Abstract Compared with traditional piezoelectric ultrasonic devices, optoacoustic devices have unique advantages such as a simple preparation process, anti-electromagnetic interference, and wireless long-distance power supply. However, current remain limited due to low damage threshold energy conversion efficiency, which seriously hinder their widespread applications. In this study, using self-healing polydimethylsiloxane (PDMS, Fe-Hpdca-PDMS) carbon nanotube composite, flexible patch is...
Single-crystal niobium nitride (NbN) thin films were fabricated at ambient substrate temperature so that photoresist lift-off techniques could be used in fabricating Josephson tunnel junctions. In this article, we describe the superconducting properties and crystal structure of NbN films. Even though substrates not heated, had excellent properties: a high Tc 16 K, low normal-state resistivity (ρ20=62 μΩ cm), residual ratios RRR=ρ300/ρ20 above one. The film structures, which investigated by...

A mild and efficient surface activation protocol to convert polycarbonate (PC) substrates, e.g., plastic bases of compact disks, biochip platforms for DNA probe immobilization target detection is described. The preparation procedure (activation, patterning, coupling) simple effective; the on-chip hybridization sensitive selective. Particularly, UV/ozone treatment PC sheets produces a hydrophilic with high density reactive carboxylic acid groups [(4.8 ± 0.2) × 10-10 mol/cm2] in less than 10...
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by the formation of new vessels, synovial proliferation and destruction articular cartilage. However, characteristic early diagnostic therapeutic monitoring methods are still lacking. We report study using photoacoustic/ultrasound (PA/US) dual-mode imaging for RA disease. By establishing collagen-induced (CIA) mouse model to classify states based on subjective grading system, PA/US allows real-time assessment erosion...
As-grown superconducting MgB2 thin films were prepared using a multiple-target sputtering system. The targets pure B and Mg metal. deposited at substrate temperatures (Ts) ranging from 207°C to 268°C on Al2O3 (1102) substrates. We found that the critical (Tc) of increased with increase Ts. film grown Ts 252°C showed highest Tc,onset value 27.8 K had sharp transition (ΔTc=0.5 K) in resistivity.
Abstract Polar metals are commonly defined as with polar structural distortions. Strict symmetry restrictions make them an extremely rare breed the constraints favor insulating over metallic phase. Moreover, no known to be magnetic. Here we report on realization of a magnetic metal phase in BaTiO 3 /SrRuO /BaTiO heterostructure. Electron microscopy reveals lattice distortions three-unit-cells thick SrRuO between layers. Electrical transport and magnetization measurements reveal that this...
