Atomic-scale insight into GaAs-based heterostructures in vertical-cavity surface-emitting lasers
Vertical-cavity surface-emitting lasers (VCSELs) are key light sources for short-reach optical interconnects, sensing, and three-dimensional imaging, where device performance and reliability criticall...
An optical displacement transducer with system-intrinsic linearity achieved by a laser diode
High-fidelity state tracking with minimal latency and compact hardware is essential for advanced vehicle suspension control systems. Self-mixing interferometry (SMI) based sensing, distinguished by it...
Observation and characterization of cusp catastrophe within a generic silicon-based DETF-type MEMS resonator
Singularities occur when the parameter space of a system folds, or comes together, to a single point. These occur in several dynamical physical systems and therefore are key to our understanding of ma...
Mg-annealing process for realizing ohmic contact on p-type Al0.6Ga0.4N while recovering ultraviolet light absorption
We have demonstrated a fabrication process for a ultraviolet (UV)-light-transparent ohmic contact layer on p-type Al0.6Ga0.4N, called the Mg-annealing process. By applying the Mg-annealing process on...
Doping-induced passivation of the Cu2ZnSnS4/MoS2 back interfaces
The performance of thin-film solar cells is often limited by interfacial defects that act as nonradiative recombination centers. In particular, Cu2ZnSnS4 solar cells suffer from dangling bonds of cati...
Exploiting the intramolecular charge transfer direction to amplify the BODIPY probe response
The high-performance fluorescent probes hinge on their intramolecular charge transfer (ICT) pathways. The unidirectional planarized intramolecular charge transfer (PLICT) and bidirectional twisted int...
Erratum: “Enhanced transport properties in GaN heterostructures with sputter-epitaxy-grown ScAlN barriers via thermal annealing” [Appl. Phys. Lett. <b>127</b> , 182103 (2025)]
Hierarchical Ti3CNTx/CNF composite films with expanded interlayer spacing for high-performance flexible micro-supercapacitors
The practical energy storage application of two-dimensional (2D) MXenes is fundamentally constrained by the restacking of nanosheets, which severely impedes ion transport kinetics. Here, we demonstrat...
High-performance ScGaN nanowire photocatalysts for photochemical nitrogen fixation under ambient conditions
In this work, scandium gallium nitride (ScGaN) nanowires are investigated for photochemical nitrogen fixation to produce ammonia (NH3). GaN nanowires, a recently reported high-performance III-nitride...
Low resistive GaN-based tunnel junctions grown at low temperatures in triple-junction LEDs
We systematically investigated growth temperature dependence on operating voltages of GaN-based tunnel junctions by metalorganic vapor phase epitaxy. Low resistive GaN-based tunnel junctions showing r...
