Energy levels of gapped graphene quantum dots in external fields
Ahmed Bouhlal, Mohammed El Azar, Ahmed Siari +1
We investigate the energy levels of fermions within a circular graphene quantum dot (GQD) subjected to external magnetic and Aharonov-Bohm fields. Solving the eigenvalue equation f…
Electron trapping in graphene quantum dots with magnetic flux
Mohammed El Azar, Ahmed Bouhlal, Abdulaziz D. Alhaidari +1
It is known that the appearance of Klein tunneling in graphene makes it hard to keep or localize electrons in a graphene-based quantum dot (GQD). However, a magnetic field can be u…
Electrons trapped in graphene magnetic quantum dots with mass term
Mohammed El Azar, Ahmed Bouhlal, Ahmed Jellal
Owing to the Klein tunneling phenomenon, the permanent confinement or localization of electrons within a graphene quantum dot is unattainable. Nonetheless, a constant magnetic fiel…
