Abstract
We investigate localized electron and hole states in parabolic quantum
dots of biased graphene bilayers in the presence of a perpendicular
magnetic field. These quantum dots can be created by means of
nanostructured gates or by position-dependent doping, which can create a
gap in the otherwise gapless dispersion of a graphene bilayer. Numerical
results show the energy levels of confined electrons and holes as a
function of the dot parameters and the magnetic field. Remarkable
crossings of energy levels are found.
