Morphology and electrical resistivity of metallic nanostructures

The electrical resistivity r of Au, Al and Cu films prepared by thermal evaporation with thickness range from 3 to 100 nm on glass substrates were studied. The r value was measured and theoretically evaluated by the Fuchs–Sondheimer (F–S), the Mayadas–Shatzkes (M–S), and the combined models. Measured r values in Al films were about seven times minor than for Au and Cu films for the minimum (3 n...

Electrical resistivity and tunneling anomalies in CeCuAs2

The compound CeCuAs2 is found to exhibit negative temperature (T) coefficient of electrical resistivity (ρ) under ambient pressure conditions in the entire T-range of investigation (45 mK to 300 K), even in the presence of high magnetic fields. Preliminary tunneling spectroscopic measurements indicate the existence of a psuedo-gap at least at low temperatures, thereby implying that this compoun...

Detection and determination of groundwater contamination plume using time-lapse electrical resistivity tomography (ERT) method

Protection of water resources from contamination and detection of the contaminants and their treatments are among the essential issues in the management of water resources. In this work, the time-lapse electrical resistivity tomography (ERT) surveys were conducted along 7 longitudinal lines in the downstream of the Latian dam in Jajrood (Iran), in order to detect the contamination resulting fro...

Inversion of Electrical Resistivity Data: A Review

High density electrical prospecting has been widely used in groundwater investigation, civil engineering and environmental survey. For efficient inversion, the forward modeling routine, sensitivity calculation, and inversion algorithm must be efficient. This paper attempts to provide a brief summary of the past and ongoing developments of the method. It includes reviews of the procedures used f...
