University of Tsukuba, the conductivity of the controllable Nano-sheet development of new electronic devices, etc. to expect

University of Tsukuba, Nims,the University of Tokyo, etc., of the joint research team of 10, the conductivity of the controllable boride hydrogen nanosheets in the successful development of announced. The research team, the new electronic devices, sensors, catalysts, etc. lead to the development of coming.

■Nano-sheet is?

Nano-sheet, and the thickness of the atoms and molecules of 1 from the A few minutes, the nanometer size of the thin film or the like. This nano-sheet, so thin, so a larger surface area, flexible, light weight, and unique electronic States, many new catalysts and electronic devices and materials, as expected. A case in point is the carbon atom 1 layer graphene, or boride molecular hydrogen number of layer consisting of boride hydrogen Nano-sheet.

Graphene has various excellent characteristics, there is a wide range of industrial fields is expected,boride hydrogen nanosheets, and the graphene to surpass the electronic device characteristics and hydrogen storage properties can theoretically anticipated.

However, the boride hydrogen nanosheets synthesis is difficult, and is realized in 2017, who was exceptional from start to finish. However, theoretical expectations against conductive, and the insulator was. Insulators in electronic device not used as.

■Boride hydrogen nanosheets conductive to having a successful

The research team, the various changing conditions to repeat the experiment,boride hydrogen nanosheets in electrically conductive in order to have that purity is important to ascertain your. That is, synthesis using organic molecules as impurities boride hydrogen nanosheets can adhere to, and the conductivity is lost was. Therefore, the boride hydrogen nanosheets with high purity can,boride hydrogen Nano-sheets with high electrical conductivity [0.13 S/cm]have not succeeded.

And by the way, the research team, according to the boride hydrogen nanosheets in organic molecules to adhere, even if conductive even,temperature is around 30 degrees to rise and the conductivity is lost, and the insulator become. However, this change is reversible,the temperature is lowered and the original conductivity is recovering. Boride hydrogen Nano-sheets of this characteristic is applied, the molecules adhere to the molecular response of the new sensor lead to the development of may be.

The research team is lightweight, flexible but conductive is controlled boride hydrogen Nano-sheet,wearable devices and other electronic devices of others,the molecular response of the sensor, further molecular adsorption using catalyst materials, etc. in the development of applications is coming.
