The signature of a double quantum-dot structure in the I-V characteristics of a complex system

We demonstrate that by carefully analyzing the temperature dependent characteristics of the I-V measurements for a given complex system it is possible to determine whether it is composed of a single, double or multiple quantum-dot structure. Our approach is based on the orthodox theory for a double-dot case and is capable of simulating I-V characteristics of systems with any resistance and capacitance values and for temperatures corresponding to thermal energies larger than the dot level spacing. We compare I-V characteristics of single-dot and double-dot systems and show that for a given measured I-V curve considering the possibility of a second dot is equivalent to decreasing the fit temperature. Thus, our method allows one to gain information about the structure of an experimental system based on an I-V measurement.Comment: 12 pages 7 figure

Acari on murine rodents along an altitudinal transect on Mauna Loa, Hawaii

Reports were scanned in black and white at a resolution of 600 dots per inch and were converted to text using Adobe Paper Capture Plug-in. Presented at IV. International Congress of Acarology, Saalfelden, Austria, August 1974; to appear with similar content in the Proceedings of congress.Rodents were trapped seasonally during a two-year period at 14 primary sites from 840 to 2440 m on a transect (with additional collecting to 2895 m), and intensively collected in the Kilauea Forest near the transect. The sampled habitats were not in the proximity of human habitations. Three of the four murine species present in the Hawaiian Archipelago were taken: Mus musculus, Rattus rattus, and R. exulans. Ectoparasites were recovered from rodents by a standardized washing technique. Mammalogical and parasitological data were analyzed by computer. The occurrence, host associations, and spatial distribution of some Acari are treated here. Significant correlations, including those for some permanently parasitic mites, are partially independent of host factors and are associated with local differences in climate.We are grateful to Professor A. Fain for providing initial determinations of the two species of nasal mites
