Fernando Ponce: Peruvian Scientific worked with Nobel Prize … – Radio Programas del Peru

‘Fernando Ponce is one of the scientists who had to go abroad to investigate the facilities you could possible not Peru. He’s probably celebrating the Nobel (Modesto Montoya) 2014 physics prize won by his colega’

The Doctor Modesto Montoya us share a note review the work of the Peruvian scientist who worked with the 90 recently awarded the Nobel Prize in Physics Shuji Nakamura

f ísicos Isamu Akasaki Hiroshi Amano and Shuji Nakamura has won the 2014 Nobel Prize in Physics for the invention of the light emitting diode , which has allowed the development of efficient white light emitters. Emitting diodes light low power consumption. A graduate physicist UNI, Fernando Ponce, worked with one of them.

From the 60s had red diodes and green. The aim was to produce white light diodes that rendered which could be obtained by combining red, green and blue. Countless laboratories unsuccessfully sought ways to produce that diode. Isamu Akasaki Hiroshi Amano and Shuji Nakamura did in early 1990.

Artificial lighting consumes a quarter of electricity so that the LEDs are essential elements to reduce energy consumption and materials . LEDs last up to 100,000 hours while incandescent bulbs only 1,000 hours and fluorescents 10,000.
The Renewable Energy Centre (ERC) of the National University of Engineering (UNI) uses project-based lighting solar cells to serve remote communities of electrical networks.

At the UNI, interest in solar energy began in the 70s, under the direction of German physicist Manfred Horn . The development of solar cells stimulated research in semiconductors. Among the students who chose this field of research was Fernando Ponce, who later went to Stanford, to now known Silicon Valley. His interest in understanding semiconductors led him to be the first to observe atomic arrangements, using electron microscopy.

Fernando Ponce is the closest to the LED Peruvian scientist. In the 90 working Shuji Nakamura, one of the Nobel , who has several joint publications award. At the time Ponce investigated in Xerox (Palo Alto, California) and Nakamura at Nichia Chemical Industries (Japan).

The Peruvian scientist investigated why the invented materials awarded by emitting light as is now known. His work is mentioned by Shuji Nakamura . Currently still looking for ways to improve the materials based on gallium nitride, indium gallium nitride and aluminum nitride and gallium, used to emit visible light and ultraviolet light. His work is funded by the Department of Energy, the National Science Foundation and Projects Agency Defense Advanced Research (DARPA).

Fernando Ponce is one of the scientists who had to leave the abroad to investigate the facilities you could possible not Peru. is probably celebrating the 2014 Nobel Prize for Physics won by his colleague. Peru should worry about creating an attractive environment for creativity, which, like the case of LED eventually generate incalculable benefits to mankind.
