Suppression of polycrystalline formation during Na–flux GaN growth on point seeds via high-temperature and high N2 pressure conditions
The Na–flux method is suitable for producing large-diameter GaN substrates using the multi-point seed (MPS) method, in which numerous tiny seed crystals are arrayed on sapphire; however, a major chall...
Detection of magnetic ordering evolution via spin Hall magnetoresistance in antiferromagnetic Cr2O3 thin films
The magnetic ordering evolution was investigated via spin Hall magnetoresistance (SMR) in antiferromagnetic Cr2O3 thin films. The SMR ratio of the Cr2O3/Pt bilayer devices exhibits a nonmonotonic temp...
Levels of substitutional copper disturbed by an oxygen atom in n-type silicon
The deep-level spectrum of n-type silicon crystals doped with copper during float-zone growth was investigated using the DLTS and Laplace-DLTS techniques. In addition to the well-known second acceptor...
Growth mechanisms of electrical breakdown channel in electro-pulse-boring under external strong magnetic fields
Electro-Pulse-Boring (EPB) generates electric breakdown channels in dielectric media to achieve efficient rock fragmentation for deep energy resource development. Strong magnetic fields have been show...
Negative differential conductance in interband cascade emitters
We report a detailed examination of multiple negative differential conductance (NDC) features with hysteresis, observed in interband cascade lasers and light emitting diodes made from six different wa...
Ventilated acoustic energy harvester based on Friedrich–Wintgen bound state in the continuum
In this work, we design and fabricate a ventilated acoustic energy harvester based on Friedrich–Wintgen bound state in the continuum (BIC), whose operating frequency can be programmed by tuning the ge...
An anisotropic α-HgS single crystal with giant second-harmonic generation
The exploration of in-plane anisotropic properties is of great significance for fundamental studies and further development of polarization-sensitive optoelectronics. In this study, the synthesis of t...
Critical behavior and magnetocaloric effect in Laves-phase Tb1−xHoxNi2 (x = 0.25–0.75) solid solutions and composites
The critical behavior around ferromagnetic–paramagnetic phase transition of polycrystalline Tb1−xHoxNi2 solid solutions (x = 0.25, 0.5, 0.75) was investigated using magnetization measurements in a mag...
Additively manufactured high-entropy alloy mimics the pressure-induced structural transition of iron
We report a pressure-induced structural phase transformation in an additively manufactured (AM) AlCrFe2Ni2 high-entropy alloy. High laser scan-speed processing during AM has been shown to strongly sup...
Optimized GaAsSb/GaAsN type-II superlattices studied by cross-sectional scanning tunneling microscopy
Short period GaAsSb/GaAsN type-II superlattices (SLs) with a bandgap between 1.00 and 1.15 eV can be grown lattice-matched to GaAs, making them suitable sub-cells to be implemented in the design of mo...
Realization of inclined-sidewall stacked Josephson junction arrays with uniform critical current via barrier layer parameter optimization
For the critical issue of wire layer cracking that tends to occur during the wire layer deposition of vertically stacked Josephson junction arrays, this paper proposes an inclined-side stack structure...
