Utilizing vicinal SiC/Si(001) wafers one can synthesize self-aligned graphene nanoribbons that exhibit energy transport gap on the order of 1 eV, large positive in-plane magnetoresistance, and the potential to work as a spin filter, opening opportunities for electronic and spintronic applications. This work demonstrates the capabilities to control the lattice and boundary orientations and the layer thickness in-situ, during the few-layer graphene synthesis in an ultra-high vacuum [1]. Supported by the RFBR (Grant Nos. 17-02-01139, 17-02-01291). [1] V.Yu.Aristov et al., ACS Nano 13, 526 (2019)
