On Tuesday in Stockholm, the Nobel Committee announced that Isamu Akasaki Hiroshi Amano and Shuji Nakamura’s invention of efficient blue light-emitting diodes will receive the Nobel Prize in physics.
“In the award-winning discovery is what was Alfred Noblowi – to the discovery of scholars give effect in the daily lives of ordinary people. Each of us many times used and seen for example. diode bulbs. Grounds for their creation have created today’s Nobel Prize winners “- told PAP prof. Roman Stępniewski from the Department of Physics, University of Warsaw.
He explained that their action is based on a class of semiconductors called nitrides, which are compounds of nitrogen with various metals is, for example. Gallium nitride, aluminum nitride. “These nitrides have been quite a long time selected candidates for this type of light sources. Already in the 70s of the last century were carried out on this extensive research. Were, however, some technological barriers, which then were not able to overcome. Just these three Japanese (one of them a citizen of the United States – ed. PAP) led to their break, allowing for efficient light source. Akasaki and Amano put milestones in this field, and Nakamura did ultimately effective light source “- described the physicist.
Research in the area that deal with this year’s Nobel Prize winners, also runs several Polish scientific centers. Studies at Warsaw University nitrides are conducted since the 90s of the twentieth century. The leading institutions whose researchers successfully investigate nitrides, please Institute of High Pressure Research. An important achievement is to obtain gallium nitride in the form of single crystals large, the Polish company Ammono.
“The Poles actually in this field are strong, and Poland is here to boast, but you have to keep the proportions. Undoubtedly, the Japanese have here more These achievements and breakthroughs did they. Poland needs a broad, serious base that does not exist. As more support from the state. far we can conduct more basic research in this area “- said prof. Stępniewski.
