Time-domain THz characterization of semiconductors across a wide doping range by combined transmission spectroscopy and ellipsometry
Terahertz (THz) time-domain techniques provide a powerful, contactless tool for probing the electrodynamic response of semiconductors. However, conventional THz transmission spectroscopy becomes incre...
THz emission driven by inverse orbital Hall effect in Te/Fe3GaTe2 heterostructures
Terahertz (THz) spintronics is an emerging interdisciplinary field that integrates the unique advantages of spin-based electronics with the rapidly evolving frontiers of THz science. To achieve effici...
Physics-guided training-free neural network for suppressing out-of-focus background in fluorescence microscopy
Fluorescence microscopy is renowned for its high sensitivity and specificity, making it a vital tool in biomedical research. However, during practical imaging, defocused background signals often intro...
Punch-through breakdown in high-voltage GaN superjunction HEMT
GaN superjunction (SJ) high-electron mobility transistors (HEMTs) have recently emerged as a promising platform for multi-kilovolt power electronics due to their superior electric field management. Ho...
Erratum: “Reduction of spin backflow with underlying bulk WSe2 in Pt/Py/Al trilayers” [Appl. Phys. Lett. <b>125</b> (7), 072405 (2024)]
Determination of the conduction band non-parabolicity parameter of heavily doped germanium epsilon-near-zero thin films
The conduction band non-parabolicity parameter C plays a crucial role in the third-order optical nonlinearity in epsilon-near-zero (ENZ) materials. While experimental C values have been reported for t...
Task-driven single-pixel salient object detection via deep semantic compression
Single-pixel imaging (SPI) is a cost-effective computational imaging technique in special spectral bands. Traditional SPI-based sensing generally follows an “imaging-first” strategy, where reconstruct...
Antiscreening and exciton binding in quasi-one-dimensional systems
We predict antiscreening of the electron–hole interaction at large distances, independent of the distribution of the electronic response across the cross section of a quasi-one-dimensional (1D) wire s...
Hybrid superinductance with Al/InAs
We report microwave spectroscopy of Josephson junction chains made from an epitaxial Al/InAs heterostructure. The chains exhibit superinductance, with characteristic wave impedance exceeding RQ=ℏ/(2e)...
Unveiling Auger recombination current component in rectification curves of silicon heterojunction solar cells
The rectification characteristics of semiconductor junctions are the basis for their application in diverse electronic and optoelectronic devices. Theoretically, the manifestation of Auger recombinati...
Tunable frequency conversion and comb generation with a superconducting artificial atom
We investigate the power spectral density emitted by a superconducting artificial atom coupled to the end of a semi-infinite transmission line and driven by two continuous radio frequency fields. In t...
Doppler-enhanced superheterodyne Rydberg microwave receiver
We report the enhanced sensitivity of the Rydberg microwave (MW) receiver by exploiting the Doppler effect in a vapor cell. A two-photon Rydberg ladder scheme is implemented via the co-propagation of...
Imaging a hidden object in time-varying scattering media with a single-pixel detector
Imaging with a single-pixel detector is challenging, when an object is hidden in time-varying scattering media. The correlation between illumination patterns and collected single-pixel light intensiti...
