Graphene/SiC/graphene photodetectors were fabricated by epitaxial graphene prepared on semi-insulated 4H-SiC (0001) using the ultra-high vacuum high-temperature thermal decomposition method. The device exhibits a maximum responsivity of 0.01 A/W, 103 UV–visible rejection ratio, and high detectivity 1.34 × 1012 Jones with ultra-low saturation dark current 3 10−13 A. Interfacial quantum states adopted at graphene/4H-SiC heterojunction for tuning Schottky barrier reverse bias. extracted heights...
N-type Mg3Sb2 is attracting increasing focus for its outstanding room-temperature (RT) thermoelectric (TE) performance; however, achieving reliable n-type conduction remains challenging due to negatively charged Mg vacancies. Doping with compensation charges generally used but does not fundamentally resolve the high intrinsic activity and easy formation of Herein, a robust structural performance obtained by manipulating migration precisely incorporating Ni at interstitial site. Density...
Abstract High‐quality ternary relaxor ferroelectric (100)‐oriented Mn‐doped 0.36Pb(In 1/2 Nb )O 3 ‐0.36Pb(Mg 1/3 2/3 ‐0.28PbTiO (Mn‐PIMNT) thin films were grown on SrRuO ‐buffered SrTiO single‐crystal substrate in a wide deposition temperature range of 550‐620°C using the pulsed laser method. The phase structure, ferroelectric, dielectric, piezoelectric properties, and nanoscale domain evolution studied. Under 620°C, hysteresis loops current‐voltage curves showed that film owned...

Abstract A compensated pyroelectric infrared (PIR) detector based on Mn‐doped 0.15Pb(In 1/2 Nb )O 3 ‐0.55Pb(Mg 1/3 2/3 ‐0.30PbTiO (Mn‐PIMNT(15/55/30)) relaxor ferroelectric single crystal was theoretically designed and experimentally fabricated. Under the current‐mode amplification circuit, voltage responsivity specific detectivity of reached 8 × 10 4 V/W@10 Hz 3.6 cm⋅Hz /W, respectively. The noise mechanism studied dominant sources at different frequencies were simulated. Even though...
A flexible global calibration method for multi-view stereo vision with non-overlapping field of view (FOV) using linear structured light projector is presented in this paper. At least three groups plane equations are utilized to calculate the rotation between any pair cameras FOV, and then closed solution translation determined based on constraint that normal vector perpendicular lines plane. Once all pairs FOV obtained, each camera relative reference position eventually computed through...
As an important part of optical-resolution photoacoustic microscopy, the acoustic lens is responsible for efficient collection signals. The spherical focused commonly used in microscopy because its detection signal focus area. However, narrow depth field limits expansion microscopy. To solve this problem, a Bessel acoustic-beam proposed. replaces concave surface with conical to generate beam non-diffraction. Using simulation model constructed by COMSOL Multiphysics, it verified theoretically...
In order to meet the requirement of low-frequency and low-voltage seismic signal acquisition from analog digital signal, a Σ-Δ modulator for ADC is designed in this paper. Using PWM principle, second-order integral modulation adopted clock FPGA used realize delta technology oversampling rate control, quantization noise sufficiently attenuated. Finally, by controlling frequency output 32kHz, 64kHz, 128kHz other low-noise 1 bit data stream, achieve modulation.

Photoacoustic imaging is a biological non-destructive and non-invasive detection method based on the photoacoustic effect. It not only has advantages of high optical accuracy, speed, contrast, but also good tissue penetration ultrasound imaging. Early diagnosis diseases, molecular optics, brain science other fields have wide range applications. However, because technology multi-modal hybrid technology, research this often requires expensive experimental equipment, operation complicated....
