Size quantization of Dirac fermions in graphene constrictions
Quantum point contacts are narrow electrical connections of a width comparable to the wavelength of the conducting electrons. Here, the authors create such contacts in graphene by etching constrictions and use them to identify ballistic transport and quantized conductance of size-confined Dirac ferm...
