Indirect-to-direct band-gap crossover in few-layer MoTe
Ignacio Gutiérrez-Lezama, Ashish Arora, Alberto Ubaldini +4
We study the evolution of the band-gap structure in few-layer MoTe crystals, by means of low-temperature micro-reflectance (MR) and temperature-dependent photoluminescence (PL)…
Surface transport and band gap structure of exfoliated 2H-MoTe crystals
Ignacio Gutiérrez Lezama, Alberto Ubaldini, Maria Longobardi +4
Semiconducting transition metal dichalcogenides (TMDs) have emerged as materials that can be used to realize two-dimensional (2D) crystals possessing rather unique transport and op…
Gate-tuned normal and superconducting transport at the surface of a topological insulator
B. Sacepe, J. B. Oostinga, J. Li +4
Three-dimensional topological insulators are characterized by the presence of a bandgap in their bulk and gapless Dirac fermions at their surfaces. New physical phenomena originati…
