The Department of Microtechnology and Nanoscience focuses on research, innovation and education within the fields of future electronics, photonics, bio- and nanosystems. A close collaboration with Swedish and international partners within academy, industry and society enables scientific excellence and creates an innovative environment. In addition to the 200 researchers and PhD students, MC2 houses a cleanroom for micro- and nanofabrication with the latest equipment.

Information about the division

The Quantum Device Physics Laboratory (QDP) at the department of Microtechnology and Nanoscience conducts research which extends over a variety of different topics. QDP is therefore divided into three sub groups: Experimental Mesoscopic Physics (EMP), Quantum Devices & Oxide Electronics (QuOx) and the Bolometer Group. Altogether, the QDP lab focuses on studying nano electronic components beyond classical electrodynamics, and explores possibilities to make quantum mechanical effects useful in practical devices.

Major responsibilities
The discovery of Topological Insulators (TIs) has revolutionized the basic notions of materials such as metals, insulators, semiconductors, superconductors, and magnets. Here the properties of a metal and of an insulator are encompassed in the very same compound leading to a new state of matter where a topology plays a fundamental role. TI materials are insulators in the bulk while possessing a conducting surface characterized by helical Dirac states, which are massless fermions with the spin locked to the momentum. The Dirac node is responsible for the novel emergent states and controls the topological protection of the surface states. The focus so far has mostly been on improving our understanding of the many fascinating properties of TI materials, but it is now becoming clear that they possess electronic properties that make them interesting for a wide range of applications.

In this project the PhD student will study and exploit the properties of 3D topological insulator materials incorporated into high frequency devices. The main driver of the project is the prospect of using a TI nanoribbon to create a topologically protected single electron transistor, the basis for single-electron charge pump that can be used as a metrological quantum current standard. A TI nanoribbon has several potential benefits over conventional materials for accurate charge pumping because of the surface states being topologically protected from back-scattering which makes it less sensitive to defects. Moreover the gapless nature of the surface states and large bulk gap allows for device operation at very high
frequencies without breakdown.
