Electrical 1/f noise is measured in thin films of CdSe, CdSe/CdS, ZnO, HgTe quantum dots and Au nanocrystals. The noise, normalized per nanoparticle, shows no systematic dependence on the nanoparticle material coupling material. However, over 10 orders magnitude, it correlates well with nearest neighbor conductance suggesting some universal magnitude these granular conductors. In hopping regime, main mechanism determined to be mobility fluctuated. metallic regime obtained gold films, drops a...
Abstract Two‐dimensional (2D) transition‐metal carbides, nitrides, and carbocyanides, known as MXenes, have attracted tremendous attention in photonics electronics because of their promising optical, electrical, mechanical properties. However, the potential MXenes‐based heterostructures for ultrafast has not yet been explored. In this study, a Ti 3 C 2 T x /graphene vertical heterostructure (TG‐VHS), an excellent saturable absorber (SA), is successfully used to generate femtosecond laser...
Abstract 2D conjugated metal‐organic frameworks (MOFs) have attracted significant attention in various fields due to their outstanding characteristics. However, the strong interlayer π–π stacking interactions, preparation of high‐quality and atomic‐scale single‐crystalline MOF structures continues pose a challenge. The investigation its nonlinear optical (NLO) property application for ultrafast photonics is still rare. Herein, ultrathin Cu 3 (HHTP) 2 Ni (HHTP =...
Skin burns that include tissue coagulation necrosis imply variations in stiffness. Dynamic phase-sensitive optical coherence elastography (OCE) is used to evaluate the stiffness of burned skin nondestructively this paper. The homemade dynamic OCE was initially verified through tissue-mimicking phantom experiments regarding Rayleigh wave speed. After being with a series temperatures and durations, corresponding structure mice were demonstrated by histological images, tomography B-scans,...
Abstract 2D conjugated metal‐organic frameworks (MOFs) with high in‐plane‐π‐conjugation are attracting significant attention in various fields owing to their outstanding electrical transport property, substantial specific surface areas, and tunable structures. However, potential ultrafast photonics has not been extensively explored.

Multi-break vacuum circuit breakers (VCBs) are the most potential approach for applying VCBs to high voltage power system. However, it has higher thermal stability requirements than normal single break due its complex structure and rated current. In this paper, a novel 363 kV/5000 A/63 kA SF6 gas insulate (GI) VCB with series parallel is proposed. To analyze temperature rise, 3D coupled electromagnetic-thermal-fluid model established based on actual size calculated by finite element method...
Vertical-conducting GaN/mirror/Si light-emitting diodes (LEDs) with thermally stable mirrors have been fabricated using a combination of wafer-bonding and laser liftoff techniques. The thermal stabilities NiO-Ag, NiO-Ag-Ni, NiO-Au-Ag their effects on the performance mirror-substrate LEDs were studied.

The characteristics and capability of a homemade all-fiber 1.54-μm pulsed coherent Doppler lidar (CDL) were validated in field experiments by comparing the detection results with collocated sounding balloons. With range gate 30 m temporal resolution 16 s at velocity–azimuth display mode, CDL ranged from 0.1 to 5 km, time sequence height position this calibrated lidar. In intercomparison balloons, discrepancy 30-s averaged measurement horizontal wind speed direction was nearly 0.7 / 5.3 deg,...
