Researchers Create Electronic Diodes Beyond 5G Performance

David Storm, a research physicist, and Tyler Growden, a National Research Council postdoctoral researcher, at the U.S. Naval Research Laboratory with their molecular beam epitaxy system that develops gallium nitride-based (GaN) semiconductors in Washington, D.C., March 10, 2020. Storm and Growden published their research on GaN semiconductor materials, which showed high yield and performance well suited for high frequency and high power electronic devices in Applied Physics Letters.

David Storm, a research physicist, and Tyler Growden, an electrical engineer, both with the U.S. Naval Research Laboratory, developed a new gallium nitride-based electrical component called a resonant tunneling diode (RTD) with performance beyond the anticipated speed of 5G. The fifth-generation network technolog

Fossil Fuel-Free Jet Propulsion with Air Plasmas

A schematic diagram of a prototype microwave air plasma thruster and the images of the bright plasma jet at different microwave powers. This device consists of a microwave power supply, an air compressor, a compressed microwave waveguide and a flame ignitor.

Humans depend on fossil fuels as their primary energy source, especially in transportation. However, fossil fuels are both unsustainable and unsafe, serving as the largest source of greenhouse gas emissions and leading to adverse respiratory effects and devastation due to global warming.
