Tunable biaxial strain device for low dimensional materials
Vincent Pasquier, Alessandro Scarfato, Jose Martinez-Castro +2
Strain is attracting much interest as a mean to tune the properties of thin exfoliated two-dimensional materials and their heterostructures. Numerous devices to apply tunable uniax…
Stripe and short range order in the charge density wave of 1T-CuTiSe
A. M. Novello, M. Spera, A. Scarfato +4
We study the impact of Cu intercalation on the charge density wave (CDW) in 1T-CuTiSe by scanning tunneling microscopy and spectroscopy. Cu atoms, identif…
STM microscopy of the CDW in 1T-TiSe2 in the presence of single atom defects
A. M. Novello, B. Hildebrand, A. Scarfato +7
We present a detailed low temperature scanning tunneling microscopy study of the commensurate charge density wave (CDW) in 1-TiSe in the presence of single atom defects. We…
Piezoresistance in silicon at uniaxial compressive stresses up to 3 GPa
J. S. Milne, I. Favorskiy, A. C. H. Rowe +2
The room-temperature longitudinal piezoresistance of n-type and p-type crystalline silicon along selected crystal axes is investigated under uniaxial compressive stresses up to 3 G…
Giant room temperature piezoresistance in a metal/silicon hybrid
A. C. H. Rowe, A. Donoso-Barrera, Ch. Renner +1
Metal/semiconductor hybrids are artificially created structures presenting novel properties not exhibited by either of the component materials alone. Here we present a giant piezor…
