#World's highest-performance single-molecule diode created As electronics miniaturization heads towards a theoretical physical limit in the tens of nanometers,
new methods of manufacturing are required to produce transistors, diodes, and other fundamental electronic components. In this vein, a new range of molecule-sized devices have been created in the laboratory,
single-molecule diode ever made, which is said to be 50 times better in performance and efficiency than anything previously produced.
Ordinary diodes are constructed usually from silicon with a p-n (positive-negative) junction created at the point of contact between a positively"doped"semiconductor (that is,
the most common function of such a diode is to permit electric current to flow in one direction only,
As such, a diode used in this way can be seen as a type of flow-control valve that is either"on"or"off".
and so these types of diodes are known as rectifiers. This on/off asymmetric behavior in the nascent field of molecule-sized electronics, on the other hand, is achieved usually by the creation of molecules that chemically emulate the p-n junction.
This is where the Columbia university scientists claim to have made significant improvements with their new single-molecule diode."

this development can also reduce potentially harmful waste from LEDS generally made from toxic elements.
LEDS are a type of device that can efficiently convert electricity to light. Unlike fluorescent and incandescent bulbs,
LEDS direct 80 percent of the energy consumed to producing light. This is made possible by the fact that LEDS do not require a filament to be heated as incandescent and fluorescent bulbs do.
LEDS can be produced by quantum dots, or tiny crystals that have luminescent properties. Quantum dots (QDS) can be made with numerous materials, some
of which are rare and expensive to synthesize, and even potentially harmful to dispose of. Some research over the past 10 years has focused on using carbon dots (CDS),
to create LEDS instead. Compared to other types of quantum dots CDS have lower toxicity and better biocompatibility,
and subsequently, LEDS. The results were published recently in Physical chemistry Chemical Physics, a journal of the Royal Society of Chemistry.
