Metal Insulator Transition in Vanadium Dioxide Hydrated by Means of the Plasma-Immersion Ion Implantation Method

Authorized by Pergament A

In the work, we explore the modification of the structure of vanadium dioxide films, as well as the metal-semiconductor phase transition in them, when hydrated by the method of plasma-immersion ion implantation. Based on a detailed X-ray analysis and the Raman spectra of the initial and hydrated films, it is shown that the plasma-ion modification of the transition and the metallization of vanadium dioxide (at a hydrogen concentration above 10at. %) are most likely associated with electron-correlation effects amplified by hydrogen implantation and an increase in the free charge carrier density in the material. Meanwhile, the structural changes at the transition practically do not manifest themselves: the hydrated metallic vanadium dioxide remains in the monoclinic phase. The results of plasma-immersion implantation are compared with experiments where other methods of hydration of vanadium dioxide are applied.

Abstract Possibilities of plasma chemical deposition of α-Si 1-x Ge x :H (x=0÷1) films undoped and doped with PH 3 or B 2 H 6 have been analyzed from the viewpoint of their application in p-i-n structures of solar cell. The optical properties are considered, and the amount of hydrogen contained in those films is determined. The film properties are found to strongly depend on the film composition and the hydrogenation level. The number of hydrogen atoms in the films is varied by changing the gas mixture composition, and IR absorption in α-Si:H and α-G e :H films is measured. The α-Si:H and а-Si 0,88 Ge 1,2 :H films were used to fabricate three-layer solar with an element area of 1,3 sm 2 and an efficiency (η) of 9.5 %.

The Erroneous Banishment of Plastics Authorized by Walter Eevers Since some months, youth is marching in the streets of several cities throughout Europe. They scream for political attention for the fight against climate change. The debates in the press and on social media go into all directions and give attention to technological solutions to fight climate change, the need for personal lifestyle adaptation but also to fights against nuclear power generation, air traffic etc. But in the margin of these protests also plastics and the use of plastics are condemned in many of these communications.
