DC conduction processes in nickel‐dimethylglyoxime films

Abstract

Thin nickel-dimethylglyoxime Ni(DMG) 2 films of amorphous and crystalline structures were prepared by vacuum sublimation on glass and p-type Si substrates. The films were characterised by X-ray diffraction. The constructed Al/Ni(DMG) 2 /Si(p) MIS devices were characterised by the measurement of their capacitance as a function of gate voltage. The dc-electrical conduction of the Ni(DMG) 2 films grown on silicon substrate were studied at room temperature and in a temperature range of 293 -323 K. The dc current-voltage data of both amorphous and crystalline insulator follow the trap-charge-limited space-charge-limited conductivity mechanism with the characteristic trap energy E t of about 0.05 eV. The total concentration and the energy distribution of the traps were determined.

DC conduction in bis(dimethylglyoximato)palladium(II) thin films

“…8 , which describe the density of defects of various types. We mention here that data of previous study on closely related compound bis(dimethylglyoximato)Ni(II) was also obeyed TSCL mechanism [26]. However, in the present study as long as n is near 2, then the conduction can be considered almost due to a discrete very narrow band of traps (localised states) being near the mobility band edge.…”

Adsorption and reduction of palladium–dimethylglyoxime complex

“…Typical e 1 values for aliphatic and polar groups substituted aliphatic compounds vary between 2 and 6, respectively. For crystalline films of bis-(dimethylglyoximato)nickel(II) complex (Ni(HDMG) 2 ) e 1 = 4.7 has been determined in agreement with the previous values [23]. According to this, d 1 is expected in the range of 3-8 Å.…”

Template-free synthesis of rectangular mesoporous carbon nanorods and their application as a support for Pt electrocatalysts

“…The XRD pattern exhibits the characteristic peaks for nickel dimethylglyoximate. 47 After carbonization of nickel dimethylglyoximate in N 2 at 500 C, the absence of the nickel dimethylglyoximate peaks and the appearance of NiO and Ni peaks indicate the carbonization of nickel dimethylglyoximate and the coexistence of Ni and NiO species in the carbonized nanocomposite (Fig. 1b).…”
