The MEST (Ministry of Education, Science and Technology) research group on LED innovation has had praises sung internationally for the results they have achieved for increasing efficiency of BLUE LED. Korea IT Times had the good fortune of encountering the group leader for the GaN/In1-xGxN/GaN/ZnO nanoarchitecture light emitting diode microarrays research group, Dr. Gyu-chul,Yi. Dr. Yi headed a research presentation of the MEST funded innovations in LED and he is also an associate professor of physics at Seoul National University and a Director of the National Creative Research Initiative center for Semiconductor Nanorods.
To put it plainly, Dr. Yi's group have a new schematic for LED based on different materials, arranged differently, into rods. Physics of semiconductors is all about schematics, materials, light, shapes and nowadays efficiency.
When asked about efficiency of their method, which is well covered in the media and beginning to be blogged, he said that the schematic and essentially their new method created two types of efficiency. The first type of efficiency created was money savings. In the drawing the old block type method is on the right and Dr. Yi's group's method is on the left. The first thing to strike you is the change in shape. That change in shape from 100 micrometers on the left to 1 micrometer on the right translates to $ for manufacturers and eventually, consumers, both because less space is needed for a similar effect, less materials and because the light is able to be dispersed from multiple sides of the nanotube.
Other types of efficiency created by the method include extraction of the light, due to the new shape that has multiple light emitting surfaces and more bling per dot.
The method is grounded in a basic geometrical approach to refining what was. The new method is 3D in structure as opposed to the old 2D method. Dr. Yi anticipates that commercialisation is only a matter of a few years away. For consumers this means deciding to hold or fold the old screen/light or consumer device that is gong to gain from these discoveries, for inventors it spells time to imagine what you can do with this and for manufacturers this means it is time to begin the offers.
