Band gaps in jagged and straight graphene nanoribbons tunable by an external electric field
Saroka, Vasil; Batrakov, K.G.; Demin, V.A.; Chernozatonskii, L.A. (Journal article; Peer reviewed, 2015)Band gap control by an external field is useful in various optical, infrared and THz applications. However, widely tunable band gaps are still not practical due to a variety of reasons. Using the orthogonal tight-binding ... -
Edge-modified zigzag-shaped graphene nanoribbons: structure and electronic properties
Saroka, Vasil; Batrakov, K.G.; Chernozatonskii, L.A. (Journal article; Peer reviewed, 2014)Control of the band gap of graphene nanoribbons is an important problem for the fabrication of effective radiation detectors and transducers operating in different frequency ranges. The periodic edge-modified zigzag-shaped ... -
Plasmon polariton deceleration in graphene structures
Batrakov, K.G.; Saroka, Vasil; Maksimenko, S.A.; Thomsen, C. (Journal article; Peer reviewed, 2012)Surface plasmon-polariton waves with low-phase speed in carbon nanostructures can be utilized for the generation of coherent terahertz radiation through the Čerenkov mechanism, the effect being especially pronounced in ... -
Zigzag-Shaped Superlattices on the Basis of Graphene Nanoribbons: Structure and Electronic Properties
Saroka, Vasil; Batrakov, K.G. (Journal article; Peer reviewed, 2016)The paper focuses on superlattices consisting of two coplanar fragments of one-layer graphene nanoribbons that have different width and are connected at an angle. Classification of such superlattices was carried out; their ...
