Extending the Near-infrared Band-edge Absorption Spectrum of Silicon by Proximity to a 2D Semiconductor
Valerio Apicella, Teslim Ayinde Fasasi, Antonio Ruotolo
Because of its low-cost, silicon is the standard material for photovoltaic conversion. Yet, its band-edge absorption spectrum is narrower than the spectrum of the solar radiation,…
Photo-spin voltaic effect and photo-magnetoresistance in proximized platinum
D. Li, A. Ruotolo
Spin orbit coupling in heavy metals allows conversion of unpolarized light into an open-circuit voltage. We experimentally prove that this photo-spin voltaic effect is due to photo…
Excitation of spin wave modes of a magnetic dot existing in a shifted vortex-state by an out-of-plane oscillating magnetic field
Yan Liu, Yan Zhou, P. Dürrenfeld +4
Excitation of spin wave modes of a vortex-state magnetic dot by an out-of-plane oscillating magnetic field is studied numerically in the presence of a static in-plane magnetic fiel…
Unification of bulk and interface electroresistive switching in oxide systems
A. Ruotolo, C. W. Leung, C. Y. Lam +3
We demonstrate that the physical mechanism behind electroresistive switching in oxide Schottky systems is electroformation, as in insulating oxides. Negative resistance shown by th…
High-quality all-oxide Schottky junctions fabricated on heavily Nb-doped SrTiO3 substrates
A. Ruotolo, C. Y. Lam, W. F. Cheng +2
We present a detailed investigation of the electrical properties of epitaxial La0.7Sr0.3MnO3/SrTi0.98Nb0.02O3 Schottky junctions. A fabrication process that allows reduction of the…
