Driving with temperature the synthesis of graphene films on Ge(110)
L. Persichetti, M. De Seta, A. M. Scaparro +8
We systematically investigate the chemical vapor deposition growth of graphene on Ge(110) as a function of the deposition temperature close to the Ge melting point. By merging spec…
Photoluminescence study of interband transitions in few-layer, pseudomorphic, and strain-unbalanced Ge/GeSi multiple quantum wells
M. Montanari, M. Virgilio, C. L. Manganelli +11
In this paper we investigate the structural and optical properties of few strain-unbalanced multiple Ge/GeSi quantum wells pseudomorphically grown on GeSi reverse-graded substrates…
Conductance Quantization in Schottky-gated Si/SiGe Quantum Point Contacts
G. Scappucci, L. Di Gaspare, E. Giovine +3
We report on the fabrication and electronic transport characterisation of Schottky-gated strongly confined Si/SiGe quantum point contacts (QPC). At zero magnetic field and T=450mK…
Conductance quantization in etched Si/SiGe quantum point contacts
G. Scappucci, L. Di Gaspare, E. Giovine +3
We fabricated strongly confined Schottky-gated quantum point contacts by etching Si/SiGe heterostructures and observed intriguing conductance quantization in units of approximately…
Low field magnetotransport in strained Si/SiGe cavities
G. Scappucci, L. Di Gaspare, F. Evangelisti +6
Low field magnetotransport revealing signatures of ballistic transport effects in strained Si/SiGe cavities is investigated. We fabricated strained Si/SiGe cavities by confining a…
