Апстракт:
The Klein effect consists of a relativistic particle travelling through a potential barrier of any height and width without the wave being attenuated. A tunnelling effect with a transmission coefficient T(E) = 1 is observed in graphene. The probability of passing through a rectangular barrier is equal to one if the resonance conditions for massive particles are met. Irrespective of the resonance conditions, a barrier of any height and width is completely transparent for normally incident massless electrons and almost transparent at angles of incidence close to zero. Due to Klein tunneling, it is not possible to localise the particles by an electrostatic potential, which is an obstacle to the technological use of graphene as an element for nanoelectronic devices.
