Shot noise, originating from the discrete nature of electric charge, is generated by scattering
processes. Shot-noise measurements have revealed microscopic charge dynamics in …

We have measured magnetoresistance of suspended graphene in the Corbino geometry at
magnetic fields up to B= 0.15 T, ie, in a regime uninfluenced by Shubnikov–de Haas …

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 …

Low frequency resistance variations due to mobility fluctuations is one of the key factors of
$1/f $ noise in metallic conductors. According to theory, such noise in a two-dimensional …

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 …

First, I wish to express my deepest gratitude to Professor Kensuke Kobayashi for his
unending guidance and scientific discussions since I belong to his group. I also want to …

In this thesis, sophisticated conductance and noise measurements were employed for
studying electron transport through suspended graphene devices in order to understand the …
