Investigations on the structural, electrical properties and conduction mechanism of CuO nanoflakes
Copper oxide (CuO) nanostructures are of particular interest because of their interesting properties and promising applications in batteries, super capacitors, solar cells, gas sensors, bio sensors, nano fluids and catalysis. In Recent past, more efforts have been received to design materials with different properties which is dependent on morphology. In this work cupric oxide nano flakes were...

متن کاملHopping models for ion conduction in noncrystals
Ion conduction in noncrystals (glasses, polymers, etc) has a number of properties in common. In fact, from a purely phenomenological point of view, these properties are even more widely observed: ion conduction behaves much like electronic conduction in disordered materials (e.g., amorphous semiconductors). These universalities are subject of much current interest, for instance interpreted in t...
متن کاملHopping conduction in Mn-doped ZnO
The dc and ac conductivities of Mn-doped ZnO were investigated at temperatures from 10 to 100 K. The temperature dependence of the dc conductivity from 10 to 100 K shows an abrupt change at ;18 K, manifesting a much lower activation energy for conduction below 18 K. From 10 to 18 K, the ac conductivity, sac(v), varies as sac(v)5Av s in the frequency range from 10 to 10 Hz with s in the range of...
متن کاملVariable range hopping conduction in semiconductor nanocrystal solids.
The temperature and electrical field dependent conductivity of n-type CdSe nanocrystal thin films is investigated. In the low electrical field regime, the conductivity follows sigma approximately exp([-(T(*)/T)(1/2)] in the temperature range 10<T<120 K. At high electrical field, the conductivity is strongly field dependent. At 4 K, the conductance increases by 8 orders of magnitude over one dec...
