Two tuners were developed for this receiver. The more sensitive one uses tetrode transistors in the RF amplifier, mixer and oscillator. Its disadvantages lie in a much higher cost and a 12 to 14 db ...
Scientists at Novosibirsk State University (NSU) have developed an innovative approach to the accelerated creation of thermally activated delayed fluorescence (TADF) materials, which can lead to ...
Organic LEDs are light emitting diodes (LEDs) that use polymers or small organic molecules as their optically active element. Development of organic LEDs is driven in particular by its potential as a ...
Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.
Abstract: The use of surface oriented Gunn oscillators and Schottky barrier diodes provides a means of obtaining improved device operation as well as optimum applications in microwave and millimeter ...
