Mesoscopic transport in 2D materials and heterostructures

This thesis presents an experimental work on electronic transport in two-dimensional (2D) van der Waals systems. The variety of the physics of the chapters reflects the exploratory character of the Ph.D. study and demonstrates the versatility and the unique properties of some of the members of the vast group of van der Waals materials. In the...

Quantum transport at oxide interfaces

The realization of interfaces between different transition metal oxides has heralded a new era of materials and physics research. Notably, it enabled a uniquely diverse set of coexisting physical properties to be combined with an ever-increasing degree of experimental control. The primary focus of this thesis is the celebrated interface between...

Weak localization in boron nitride encapsulated bilayer MoS2

We present measurements of weak localization on hexagonal boron nitride encapsulated bilayer MoS2. From the analysis we obtain information regarding the phase coherence and the spin diffusion of the electrons. We find that the encapsulation with boron nitride provides higher mobilities in the samples, and the phase coherence shows improvement...

Electronic and superconducting properties of the two-dimensional electron system at the LaAlO3/SrTiO3(111) interface

"This thesis describes research that was executed as a combined Master Research Project in Applied Physics and Materials Science and Engineering, leading up to a double MSc degree." The (100)-oriented LaAlO3/SrTiO3 (LAO/STO) interface has been subject of intense study since the discovery of the two-dimensional electron system (2DES) in this...
