Transmissions in gapped graphene exposed to tilting and oscillating barriers
Miloud Mekkaoui, Ahmed Jellal, Abderrahim El Mouhafid
We investigate the transmissions of fermions through gapped graphene structures by employing a combination of double barrier tilting and a time-oscillating potential. The latter in…
Effect of parallel magnetic field on Klein tunneling in and graphene trilayer junctions
Abderrahim El Mouhafid, Ahmed Jellal
The effect of a parallel magnetic field and a potential substrate on the transmission, conductivity, and Fano factor of a biased ABC-stacked and trilayer graphene ju…
Klein tunneling through double barrier in ABC-trilayer graphene
Abderrahim El Mouhafid, Ahmed Jellal, Miloud Mekkaoui
Klein tunneling and conductance for Dirac fermions in ABC-stacked trilayer graphene (ABC-TLG) through symmetric and asymmetric double potential barriers are investigated using the…
Band structure and Klein paradox for a pn junction in ABCA-tetralayer graphene
Abderrahim El Mouhafid, Ahmed Jellal
We investigate the band structure of ABCA-tetralayer graphene (ABCA-TTLG) subjected to an external potential applied between top and bottom layers. Using the tight-binding mode…
