1. Time-resolved detection of temporally correlated, single-charge tunnelling
Abstract : We report real-time detection of the single charges that constitute a small electrical current, as they flow through a nano-electronic device. This represents a direct demonstration of charge discreteness in an electrical current. READ MORE

2. Cold-Electron Bolometer with Superconductor-Insulator-Normal Metal Tunnel Junctions
Abstract : The Cold-Electron Bolometer (CEB) is an ultrasensitive device designed for the detection of radiation in the terahertz region of the electromagnetic spectrum. The key to its sensitivity is the electron cooling of the absorber by the superconductor-insulator-normal metal (SIN) tunnel junction. READ MORE

3. Spatial Vision in Bees : Behavioural investigation of spatial resolution and contrast sensitivity
Abstract : Bees use multiple sensory modalities to perform day-to-day tasks. Light allows them to perceive objects and the general features of their surroundings, enabling them to find food and to navigate safely across the landscape. READ MORE

4. Time-dependent relaxation of charge and energy in electronic nanosystems
Abstract : The study of the dynamics of strongly confined, interacting open quantum systems has attracted great interest over the past years, due to potential applications in nanoelectronics, metrology as well as quantum information. Most recent experimental and theoretical research in this field has shifted attention towards electronic heat currents, recognizing their potential for practical purposes as well as for tests of fundamental theories, and also aiming to control the inevitable heat dissipation of any dynamically operated electronic device.

5. Magnetoresistance and Space : Micro- and Nanofeature Sensors Designed, Manufactured and Evaluated for Space Magnetic Field Investigations
Abstract : In recent years, the interest for miniaturization of spaceborne instruments and subsystems has increased steadily, as this enables development of small and lightweight satellite classes as well as more versatile payloads on traditional spacecraft. In essence, this thesis work is an investigation of the applicability of magnetoresistive technology to a magnetometer intended for space. READ MORE
