A symmetric gain optoelectronic mixer based on an indium gallium arsenide (In0.53Ga0.47As)/indium phosphide (InP) symmetric heterojunction phototransistor structure is being investigated for chirpedAM laser detection and ranging (LADAR) systems operating in the ‘‘eye-safe” 1.55 lm wavelength range. Signal processing of a chirped-AM LADAR system is simplified if the photodetector in the receiver...

In this work, we report a novel and feasible strategy for the practical applications of one-dimensional ultrasensitive phototransistors made of tungsten-doped VO2 single nanowires. The photoconductive response of the single nanowire device was investigated under different visible light excitations (405 nm, 532 nm, and 660 nm). The phototransistor device exhibited ultrafast photoresponse, high r...

The intensity and quality of the X-Rays a patient receives is determined by exposure factor. Voltage (kV), Current (mA), Time (seconds), tube-to-film distance (FFD) are factors that can be controlled determined. key factor determine tube voltage (kV) which affects to penetrate objects. purpose this research improve image relatively affordable manufacturing costs obtaining difference in detector...

Recent research interest in organic field-effect transistor (FET) memory has shifted to the functionality of photoprogramming terms its potential uses multibit data storage and light-assisted encryption low-energy consumption broad response various optical bands. Phototransistor can be modulated through both electrical stress light illumination, allowing it function as an orthogonal operation m...

Detecting bubble in two-phase flow has been a basic issue in two-phase flow systems. A new method for measuring the frequency of bubble formation is presented in this paper. For this purpose, an electronic device was designed and constructed which works based on a change in intensity of laser beam. For this purpose, continues light beam is embedded just above the needle, which is received by a ...

Self-Healing Devices An innovative concept of a self-healed electrode-channel system employing ultrathin metallic copper monosulfide (CuS) and monolayered molybdenum disulfide (MoS2) is demonstrated by John Hong, SeungNam Cha, co-workers in article number 2102091 for the design defect-curable transistors phototransistors. Excess sulfur adatoms from CuS electrode spontaneously heal defect sites ...
