Charging effects in niobium nanostructures
Torsten Henning
Three types of metallic nanostructures comprising niobium were investigated experimentally; in all three types, electric transport at very low temperatures was governed by Coulomb…
Bias and temperature dependence of the noise in a single electron transistor
Torsten Henning, B. Starmark, T. Claeson +1
A single electron transistor based on Al-AlO_x-Nb tunnel junctions was fabricated by shadow evaporation and in situ barrier formation. Its output current noise was measured, using…
Gain Dependence of the Noise in the Single Electron Transistor
B. Starmark, Torsten Henning, A. N. Korotkov +2
An extensive investigation of low frequency noise in single electron transistors as a function of gain is presented. Comparing the output noise with gain for a large number of bias…
Magneto-photoluminescence studies of Zn_{1-x}Mn_xTe/ZnTe multiple quantum-well and quantum dot structures
Ivan J. Griffin, Peter J. Klar, Daniel Wolverson +4
Wide quantum dots were fabricated from multiple quantum well structures based on Zn_{1-x}Mn_xTe/ZnTe (x = 0.076) dilute magnetic semiconductors and were investigated via photolumin…
Photoluminescence and photoluminescence excitation studies of lateral size effects in Zn_{1-x}Mn_xSe/ZnSe quantum disc samples of different radii
P. J. Klar, D. Wolverson, J. J. Davies +3
Quantum disc structures (with diameters of 200 nm and 100 nm) were prepared from a Zn_{0.72}Mn_{0.28}Se/ZnSe single quantum well structure by electron beam lithography followed by…
Coulomb blockade effects in anodised niobium nanostructures
Torsten Henning
Niobium thin film nanostructures were fabricated using electron beam lithography and a liftoff process involving a four layer resist system. Wires having micrometres in length and…
Comparison of Zn_{1-x}Mn_xTe/ZnTe multiple-quantum wells and quantum dots by below-bandgap photomodulated reflectivity
P. J. Klar, D. Wolverson, D. E. Ashenford +2
Large-area high density patterns of quantum dots with a diameter of 200 nm have been prepared from a series of four Zn_{0.93}Mn_{0.07}Te/ZnTe multiple quantum well structures of di…
Characterisation of HTSC ceramics from their resistive transition
Torsten Henning, H. Kliem, A. Weyers +1
The resistivity vs. temperature relation in bulk ceramic HTSC under self-field conditions as well as in weak external magnetic fields is modelled by local Lorentz force induced flu…
Coulomb blockade effects in anodised niobium nanostructures
Torsten Henning, D. B. Haviland, P. Delsing
Niobium thin film wires were fabricated using electron beam lithography with a four layer liftoff mask system, and subsequently thinned by anodisation. The resistance along the wir…
