American scientists have created a nanoscale LED 100 times brighter than usual

As you know, standard LEDs are flat designs that are produced in much the same way as transistors.

In the case of transistors, there is already a new technology that allows vertical channels (FinFET) and thus pass huge currents through the transistors.

But somehow no one thought to put LEDs on edge and thereby make them work much more efficiently. But American scientists succeeded in experimenting with an LED. And the results are as follows.

Who came up with the idea to put the LED "on the priest"

The experiment was led by representatives of the US National Institute of Standards and Technology (NIST), and was attended by an engineer from the University of Maryland, Rensselaer Polytechnic and the IBM Research Center.

Together, a theoretical basis was developed, and then a new LED structure was embodied in a real experiment.

So practical tests of the new design have shown simply amazing results:

The experimental LED showed a huge increase in the brightness of the glow, which became possible transform an LED into a semiconductor laser without specialized devices (resonators, etc.).

So, in comparison with standard submicron LEDs, the new experimental LED demonstrated a brightness increase of 100-1000 times.

This is an amazing result, because the scientists used standard components to implement the LED - gallium nitride, zinc oxide, titanium and gold (components of super bright LEDs).

How the new LED is implemented

The only difference is in the shape of the LEDs. During numerous experiments, scientists created an LED from elongated thin filaments of zinc oxide, which were called fins.

Each such structure is only 5 microns wide, but in length it can be up to a centimeter or even more (thus, the characteristics of the product will be set).

As in the variant with FinFET - transistors, it was possible to supply current to the new LED even through the side edges.

So the practical tests greatly surprised the scientists, because the vertical structure created in this way emitted a luminous flux with a power of 20 μW, and a classic LED of a similar size gave out only 22 nW, in other words, it was 100-1000 times less.

Another unique discovery was the fact that with an increase in the strength of the passing current, the glow LED from a wide spectrum was sharply shifted into radiation of only two waves in the ultraviolet range.

That is, in other words, with a slight movement of the hand, the LED was transformed into a semiconductor laser.

This unique discovery opens up the broadest prospects in the production of new next-generation electronic devices.
