Device based on two-dimensional oxide interface superconductors can be “edited” using atomic force microscope lithography ...

The effective control of heat transfer is important in improving energy efficiency. The thermal diode is one of the key elements of heat flow control. Like the current rectification effect found in ...

A diode is a device that allows current to flow in one direction but not in the other. This ability makes diodes useful in many applications, including converting AC to DC, regulating voltages, and ...

This lab seeks to illustrate the fundamental operation of uncontrolled rectifier circuits. The waveforms associated with these circuits are visualized using simulation and experimentation. The circuit ...

Under the direction of Latha Venkataraman, associate professor of applied physics at Columbia Engineering, researchers have designed a new technique to create a single-molecule diode, and, in doing so ...

The word “ideal” is often used in introductory engineering classes as a starting point to describe a component. However, at some point in any actual project or design, reality sets in, as there’s no ...

Researchers have created a diode out of a 1 nm-sized single molecule with high rectification ratios. Diodes, commonly used in in everyday electronic devices, allow current to flow in one direction ...

Forty years ago, scientists theorized that a single molecule could function as a diode—an electronic circuit element that allows current to flow in one direction but not the other. In the ongoing push ...

The effective control of heat transfer is of great significance to improve energy efficiency. Thermal diode is one of the key elements for heat flow controlling. Similar to the current rectification ...
