The most efficient single-molecule diode ever made

Researchers have created the most efficient single-molecule diode ever.

Diodes are common in everyday electronic devices, in which they control the current by allowing it to flow in one direction while blocking it in the opposite direction. The researchers, working at the University of Barcelona (UB) and IBEC, have created one of just 1 nanometer in size with a rectification ratio – the ratio of the current that flows in one direction compared to the other – several orders of magnitude higher than previously.

IBEC/UB team to take part in battle of artificial noses

Two undergraduate biomedical engineering students who are doing their practical work at IBEC have been selected to go to Montreal to compete in SNIFFEST, a new international competition promoting practical and original solutions for odour measurement.

The UB-IBEC team, third year students Alba Iruela and Suhyang Park, have built a system based on chemical sensors and a Raspberry Pi in Santiago Marco’s Signal and Information Processing for Sensing Systems group at IBEC, which is also sponsoring half the cost of their trip. The system contains embedded intelligence algorithms which the students have programmed to analyze the signals from the sensors.
