Jesper Nygård's primary research areas are within solid state physics and nanophysics. We explore quantum effects in semiconductor nanostructures, focusing on devices for nanoelectronics, novel biosensors and quantum information processing.

Research
The work is based on advanced nanofabrication, electrical measurements, and experiments at ultralow temperatures. Devices are typically based on unconventional materials such as carbon nanotubes, graphene and semiconductor nanowires. Our group hosts a cleanroom with a suite of nanofabrication tools, including molecular beam epitaxy, electron microscopes and electron beam lithography systems.

In the field of bionanoelectronics, we develop semiconductor biosensors in collaboration with the Nanobiotechnology group and within the UNIK Synthetic Biology project. Examples are nanowire field-effect sensors for pH and protein sensing and nanowire arrays for probing of individual cells based on fluorescent techniques or electrical probing.

This work may lead to a variety of future applications such as integrated nanoelectronics, sensor technology, spintronics, qubits for quantum computing, sources of entangled electrons for quantum information, and photovoltaics. The group has spun out three startup companies.
