We study the transmission of electron beams with a finite angular
extent through symmetric andasymmetric multi-barrier structures in
graphene with the aim of enhancing the functionality ofnanodevices.
The barriers in graphene are created by applying electrostatic
voltages on narrow gateelectrodes. We found that, besides
modulating the transmission coefficient of obliquely
incidentelectrons, such structures can narrow electron beams, split
them into two parts with tunableintensities, and even steer them by
slightly modifying the gate voltage.
В этой статье исследовано поведение электронов в графеновых
структурах с периодическим потенциалом. Предложены различные
применения этих структур и доказано их приеимущество перед
используемыми аналогами.
