We present a theory of interacting valence holes in a gate-defined one-dimensional
quantum channel in a single layer of a transition metal dichalcogenide material WSe 2 …

We present here a theory of excitonic complexes in gated WSe 2 quantum dots (QDs). The
QD gate potential causes type-II band alignment, ie, electrostatically confines holes and …

We describe here a theory of a quantum dot in an electrically tunable MoSe $ _2 $/WSe $ _2
$ heterostructure. Van der Waals heterostructures allow for tuning their electronic properties …

We explore the possibility of attaining valley-dependent tunnelling and confinement using
proximity-induced spin-orbit couplings (SOCs) in graphene-based heterostructures. We …

Various properties of interlayer excitons in double-layer transition metal dichalcogenides
quantum dots are analyzed using a low-energy effective Hamiltonian with Coulomb …

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 …
