Carbon nanotube as quantum point contact valley-filter and valley-splitter
Naif Hadadi, Adel Belayadi, Ousmane Ly +1
The electrical characteristics of a carbon nanotube can be significantly modified by applying elastic strain. This study focuses on exploring this phenomenon in a single-walled car…

Valley-dependent tunneling through electrostatically created quantum dots in heterostructures of graphene with hexagonal boron nitride
A. Belayadi, N. A. Hadadi, P. Vasilopoulos +1
Kelvin probe force microscopy (KPFM) has been employed to probe charge carriers in a graphene/hexagonal boron nitride (hBN) heterostructure [Nano Lett, 21, 5013 (2021)]. We propose…

Pseudo Electric Field and Pumping Valley Current in Graphene Nano-bubbles
Naif Hadadi, Adel Belayadi, Ahmed AlRabiah +6
The extremely high pseudo-magnetic field emerging in strained graphene suggests that an oscillating nano-deformation will induce a very high current even without electric bias. In…
