We predict here the fine structure of an electrically tunable negatively charged exciton (trion)
composed of two electrons and a hole confined in a gated bilayer graphene quantum dot …

Single-layer quantum dot gate potential causes type-II band alignment, ie electrostatically
confines holes and repels electrons, or vice versa. Hence, the confinement of excitons in …

We determine the optical properties of gated bilayer graphene quantum dots with trigonal
warping (TW) of single-particle energy spectra. The lateral structure of metallic gates …

In this thesis, we study graphene's optical and electrical properties, primarily focusing on
bilayer graphene (BLG) quantum dots (QDs). We discuss a tight-binding model to accurately …
