Voltage control of the quantum scattering time in InAs/GaSb/InAs trilayer quantum wells
New Journal of Physics, 2023 We study the evolution of the quantum scattering time by gate voltage training in the topological insulator (TI) based on InAs/GaSb/InAs trilayer quantum wells.

In-Well and Barrier Coupling Pump of Semiconductor Disk Laser
IEEE Photonics Journal, 2022 We report an in-well and barrier coupling pump scheme of semiconductor disk laser (SDL). An in-well-absorbed (940 nm) and a barrier-absorbed (808 nm) pump source were used to measure laser output characteristics. The output power of the coupling pump can

Optical Gain Characteristics of BGaAs/GaP Quantum Wells
IEEE Photonics Journal, 2020 Light emitters integrated with Si platform are highly desirable for photonic integrated circuits, however, manufacturing them remains difficult. In this work, BGaAs/GaP quantum well (QW) structures are proposed as a promising solution of the ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

FEBS Letters, EarlyView.Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...
