(author), Watanabe, Kenji (author), Castellanos-Gomez, Andres (author)In two-dimensional materials research, oxidation is usually considered as a common source for the degradation of electronic and optoelectronic devices or even device failure. However, in some cases a controlled oxidation can open the possibility to widely tune the band structure of 2D materials. In particular, we demonstrate the controlled...journal article 2020

(author), Ferrer, Isabel J. (author), D'Agosta, Roberto (author), Castellanos-Gomez, Andres (author)TiS<sub>3</sub> nanosheets have proven to be promising candidates for ultrathin optoelectronic devices due to their direct narrow band-gap and the strong light-matter interaction. In addition, the marked in-plane anisotropy of TiS<sub>3</sub> is appealing for the fabrication of polarization sensitive optoelectronic devices. Herein, we study...journal article 2018

(author), D'Agosta, R. (author), Castellanos Gomez, A. (author)We present characterizations of few-layer titanium trisulfide (TiS3) flakes which, due to their reduced in-plane structural symmetry, display strong anisotropy in their electrical and optical properties. Exfoliated few-layer flakes show marked anisotropy of their in-plane mobilities reaching ratios as high as 7.6 at low temperatures. Based on...journal article 2016
