Electrical properties of MIS structures with silicon nanoclusters
The theoretical and experimental investigations of electrical properties of the Al-SiO2- -SiO ( ncs Si − 2-Si structures grown using high temperature annealing SiOx, x < 2, have been carried out. It has been experimentally found that the Al-SiO2- ( ) ncs Si − -SiO2-Si structures with the tunnel dielectric layer revealed the effect of dynamic memory. Electric properties and parameters of the interface states located between and SiO ncs Si− 2 were studied in detail by measuring of current-voltage, capacitance-voltage, and thermally stimulated current characteristics.
Peculiarities of electron transport in SiOx films obtained by ion-plasma sputtering
The electrical conductivity of SiOx and nanocomposite SiO2(Si) films obtained by ion-plasma sputtering with subsequent high-temperature annealing has been investigated. On the basis of the detailed analysis of the current characteristics some electric parameters have been calculated and mechanisms of the electrical conductivity of the SiOx and SiO2(Si) films have been determined. The electrical conductivity of the films is based on the mechanism of hopping conductivity with variable-range hopping through the traps near the Fermi level (Mott’s mechanism). The minimum of current in current–voltage characteristics has been revealed in the temperature range 78–225 K. The qualitative model for explanation of the features of electron transport in SiOx and SiO2(Si) films has been proposed.
Suppressed Light Emission of the Reaction Zone in Detonation
THE detonation of high explosives in water can be photographed with an open camera and a flash light as the explosive gases do not emit light. The method has been used1 to investigate the spread of shock waves and explosive gases, and to investigate the initiation by shock waves2. We have found that it can be used also in certain gases such as butane and propane. The method is not suitable, on the other hand, for explosives with two levels of detonation velocity in the case of low velocity. A great part of the reaction then occurs after the reaction zone has passed and the expanding explosive gases are very luminous even in water.
