Abstract Topological superconductivity is central to a variety of novel phenomena involving the interplay between topologically ordered phases and broken-symmetry states. The key ingredient an unconventional order parameter, with orbital component containing chiral p x + i y wave term. Here we present phase-sensitive measurements, based on quantum interference in nanoscale Josephson junctions, realized by using Bi 2 Te 3 topological insulator. We demonstrate that induced consistent...
Early-onset lung cancer in young adults represents a less studied clinical entity with increasing incidence which still affects large number of patients. Here we perform comprehensive analysis early-onset for the clinicopathological features, genomic alterations, gene expression, and immune landscape by establishing cohort enrolling 421 non-small cell (NSCLC) patients from ten medical centers China. Comparative reveals distinct alteration between younger elder NSCLC, ERBB2 mutations...
Under the guidance of national 'double innovation' development strategy,some effective methods, such as updating concepts, improving evaluation system, and changing supervision functions, introduction diversified methods etc, have been adopted to address problems existing in teachers' teaching quality our school order promote self-improvement self-improvement. The method mathematical fuzzy level analysis has used implement scientifically objectively. It plays a positive role promoting...
Due to high responsivity and wide spectral sensitivity, metal halide perovskite photodiodes have a range of applications in the fields visible light near-infrared photodetection. Specific detectivity is an important quality factor for high-performance perovskite-based photodiodes, while one keys achieving reduce dark current. Here, 3-fluoro phenethylammonium iodide (3F-PEAI) was used passivate surface form two-dimensional (2D) on three-dimensional (3D) surface. The as-fabricated passivated...
Heterogeneous integration of compound semiconductors on a Si platform leads to advanced device applications in the field photonics and high frequency electronics. However, unavoidable bubbles formed at bonding interface are detrimental for achieving yield dissimilar semiconductor by direct wafer technology. In this work, lateral outgassing surface trenches (LOTs) introduced efficiently inhibit bubbles. It is found that chemical reactions InP–Si similar those Si–Si bonding, generated gas can...
A previously unreported phase transition between Bi2Te3 and Bi4Te3 in bismuth telluride grown by molecular beam epitaxy is recorded via XRD, AFM, SIMS observations. This found to be related the Te/Bi equivalent pressure (BEP) ratio. BEP ratios below 17 favor formation of while formed at higher ratios. Transport measurements reveal that has electron mobility than Bi4Te3.
We present high-reflectivity mechanical resonators fabricated from AlGaAs heterostructures for use in free-space optical cavities operating the telecom wavelength regime. The are slabs of GaAs and patterned with a photonic crystal to increase their out-of-plane reflectivity. Characterization modes reveals residual tensile stress device layer. This results higher frequencies than unstressed can be used strain engineering dissipation. Simultaneously, we find that finite waist incident beam...
Temperature dependence of intersubband transitions in AlN/GaN multiple quantum wells grown with molecular beam epitaxy is investigated both by absorption studies at different temperatures and modeling conduction-band electrons. For the study, sample heated increments up to $400^\circ$C. The self-consistent Schr\"odinger-Poisson includes temperature effects band-gap influence thermal expansion on piezoelectric field. We find that energy decreases only $\sim 6$ meV $400^\circ$C relative its room value.
