III–V semiconductor light-emitting diodes (LEDs) on Si substrates, suitable for large-scale and large-wafer-size manufacturing, are a convenient option on-chip light sources. Here, we present the design fabrication of MoS2 nanosheet-decorated InGaN/AlGaN/GaN LED substrate with Fabry–Perot waveguide, utilizing standard microfabrication processes. We assess voltage–current characteristics, electroluminescence (EL) properties, polarization chrominance, surface temperature device. The layer's...
We have developed a position-sensitive Parallel Plate Avalanche Counter (PPAC) to detect the fission fragments and reconstruct reaction plane in experiment of studying nuclear equation state (nEOS) by means heavy ion collision (HIC).
