In two-dimensional systems, perpendicular magnetic fields can induce a bulk band gap and
chiral edge states, which gives rise to the quantum Hall effect. The quantum Hall effect is …

We present a device architecture of hybrid-edge and dual-gated quantum point contact. We
demonstrate improved electrostatic control over the separation, position, and coupling of …

We explore the non-equilibrium transport regime in graphene using a large dc current in
combination with a perpendicular magnetic field. The strong in-plane Hall field generated in …

Breakdown of the quantum Hall effect (QHE) is commonly associated with an electric field
approaching the inter-Landau-level (LL) Zener field, the ratio of the Landau gap and the …

The Coulomb excitations of charge density oscillation are calculated for a double-layer
heterostructure. Specifically, we consider two-dimensional (2D) layers of silicene and …

Magnetic ordering in low dimensional semiconducting structures is an important element for
spin-based electronics. Zigzag graphene nanoribbons which sustain ferromagnetic edge …

This thesis addresses three different phenomena in the DC and GHz electronic transport
properties of ballistic, hBN-encapsulated graphene: Firstly, the total internal reflection of …
