Method for 3D Nonlinear Structured Illumination Super-resolution Imaging
Researchers at the University of Arizona have developed a super-resolution microscopy method that is faster, easier to use, and has less artifacts than current super-resolution methods. The result is a 3D dual-color stimulated emission depletion (STED) nonlinear structured illumination (NL-SIM) microscope. Using a combination of low coherent light and...

Real-Time Base Line Correction Method
The generation and recombination of mobile charge carriers (electrons and electron holes) are two vital fundamental processes determining semiconductor performance. The minority character lifetime is a measurement of the recombination and generation rates of mobile charge carriers. Time-resolved Photoluminescence (TRPL) is a measurement of the minority...

Low-Voltage Charge-Coupled Devices with a Heterostructure Charge-Storage Well
The charged-coupled device (CCD) is commonly known for its applications in digital cameras and infrared photodetectors. Although this device has been revolutionary within imaging applications, there are some shortcomings that can be improved. For instance, a conventional CCD requires a very high external voltage. High power consumption means that portable...

Double Heterostructure Solar Cells and Photodetectors Based on MgCdTe Absorbers
Multi-layered CdTe solar cell devices have properties that are promising but face low conversion efficiencies and high manufacturing costs. In contrast to typical monocrystalline Si and GaAs materials, CdTe cells are made up of polycrystalline materials and thus, have poor open circuit voltages which are responsible for the low efficiencies. Therefore,...

Two-terminal multicolor photo-detectors (PD) and focal plane arrays (FPA)
The state of the art of two-color focal plane arrays (FPAs) are two or three terminal photo detector pixels integrated with electronic readout circuits (ROICs). However, a multicolor (> 2) photodetector pixel requires many more terminals, making it very difficult, if not impossible, to integrate multicolor pixel arrays to ROICs due to the increase...
