diamond-structured photocrystalline assembly simulating enzyme bonds
- Like enzymes, selective bindings of shapes are induced between nanoparticles to form a diamond structure.
- Expected use for ultra-high efficient solar cells, displays, and ultra-small lasers in the future
- Publish Nature 9.24 (Thursday)
Based on the mass synthesis technology of patch nanoparticles published in Nature in 2017, the research team led by Professor Lee Ki-ra of the Department of Chemical Engineering said that they succeeded in inducing "selective binding according to shape" between nanoparticles and forming a diamond structure at once by introducing DNA selectively only to certain parts of patch nanoparticles.
It is expected that these diamond structures will be able to completely trap or control light, which will be used to develop various optical devices such as ultra-high-efficiency solar cells, displays, and ultra-small lasers in the future.
The diamond-type optical crystal structure developed by the research team is a crystal structure in which nanoparticles are arranged in a three-dimensional space, such as a diamond crystal structure made of carbon. This is all the more significant in that the diamond-type photorecrystalline structure, which has remained unsolved since 1990 when it was reported that it was an excellent photorecrystalline structure, has become experimentally feasible at the wavelength-size level of light.
In 2017, the research team announced in Nature Materials that diamond structure and pyrochloro structure can be implemented through research using Laves structure that interpenetrate with each other, and based on this, they have been conducting research to implement photo-crystal structure. This study is the result of a new proposal and implementation in the discussion process to simplify the second stage manufacturing process.
The photo-crystalline of diamond crystal structure has a wide light-band gap, and if implemented, light can be controlled in various forms in three-dimensional space.
"This study embodies a three-dimensional diamond photorecrystalline structure that has not been solved for a long time," Professor Lee Ki-ra said. "It is expected that solar cells, displays, lasers, sensors, etc. based on the photorecrystalline structure, as well as photomultiplier devices and optical computers can be used."
This study was conducted with the support of the Nano and Material Technology Development Project (Challenge Type Research) project of the Ministry of Science and ICT, and was conducted jointly with Professor David Pine of New York University and Professor Stepano Sanana of New York University. The research results were published in the journal Nature in 9.24 (Thursday).
