Journal ArticleDOI
Evidence of the direct-to-indirect band gap transition in strained two-dimensional WS 2 , MoS 2 , and WSe 2
Elena Blundo,Marco Felici,Tanju Yildirim,Giorgio Pettinari,Davide Tedeschi,A. Miriametro,Boqing Liu,W. Ma,Yuerui Lu,Antonio Polimeni +9 more
TL;DR: In this article, the effects of high strain on the optoelectronic properties of 2D crystals were investigated and the possibility to induce a clear-cut crossover from direct to indirect bandgap in strained monolayers was demonstrated.
Journal ArticleDOI
Influence of bismuth incorporation on the valence and conduction band edges of GaAs1−xBix
Giorgio Pettinari,Antonio Polimeni,Mario Capizzi,J.H. Blokland,Peter C. M. Christianen,J.C. Maan,Erin C. Young,Thomas Tiedje +7 more
TL;DR: In this article, the electronic properties of GaAs1−xBix were investigated by photoluminescence at variable temperature (T=10−430K) and high magnetic field (B=0-30T).
Journal ArticleDOI
Interaction between conduction band edge and nitrogen states probed by carrier effective-mass measurements in Ga As 1 − x N x
Francesco Masia,Giorgio Pettinari,Antonio Polimeni,Marco Felici,A. Miriametro,Mario Capizzi,A. Lindsay,S.B. Healy,Eoin P. O'Reilly,A. Cristofoli,G. Bais,M. Piccin,Silvia Rubini,Faustino Martelli,A. Franciosi,Peter J. Klar,Kerstin Volz,Wolfgang Stolz +17 more
TL;DR: In this paper, the electron effective mass was determined by magnetophotoluminescence in as-grown and hydrogenated samples for a wide range of nitrogen concentrations (from 0.01% to 1.78%).
Journal ArticleDOI
Reducing the impact of radioactivity on quantum circuits in a deep-underground facility
Laura Cardani,Francesco Valenti,N. Casali,Gianluigi Catelani,Thibault Charpentier,Massimiliano Clemenza,I. Colantoni,Angelo Cruciani,L. Gironi,Lukas Grünhaupt,Daria Gusenkova,Fabio Henriques,Marc Lagoin,M. I. Martínez,Giorgio Pettinari,C. Rusconi,Oliver Sander,Alexey V. Ustinov,Marc Weber,Wolfgang Wernsdorfer,M. Vignati,Stefano Pirro,Ioan Pop +22 more
TL;DR: Operating in a deep-underground lead-shielded cryostat decreases the quasiparticle burst rate by a factor thirty and reduces dissipation up to a factor four, showcasing the importance of radiation abatement in future solid-state quantum hardware.
Journal ArticleDOI
Controlled Micro/Nanodome Formation in Proton-Irradiated Bulk Transition-Metal Dichalcogenides.
Davide Tedeschi,Elena Blundo,Marco Felici,Giorgio Pettinari,Boqing Liu,Tanju Yildrim,Elisa Petroni,Chris Zhang,Yi Zhu,Simona Sennato,Yuerui Lu,Antonio Polimeni +11 more
TL;DR: Lithographic techniques provide a means to engineer the formation process so that the domes can be produced with well-ordered positions and sizes tunable from the nanometer to the micrometer scale, with important prospects for so far unattainable applications.
