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)…
Collapse of the Mott gap and emergence of a nodal liquid in lightly doped SrIrO
A. de la Torre, S. McKeown Walker, F. Y. Bruno +13
Superconductivity in underdoped cuprates emerges from an unusual electronic state characterised by nodal quasiparticles and an antinodal pseudogap. The relation between this state…
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…
Progress in organic single-crystal field-effect transistors
Ignacio Gutiérrez Lezama, Alberto F. Morpurgo
Research on organic thin-film transistors tends to focus on improvements in device performance, but very little is understood about the ultimate limits of these devices, the micros…
Threshold voltage and space charge in organic transistors
I. Gutiérrez Lezama, A. F. Morpurgo
We investigate rubrene single-crystal field-effect transistors, whose stability and reproducibility are sufficient to measure systematically the shift in threshold voltage as a fun…
Quantitative analysis of electronic transport through weakly-coupled metal/organic interfaces
A. S. Molinari, I. Gutierrez Lezama, P. Parisse +3
Using single-crystal transistors, we have performed a systematic experimental study of electronic transport through oxidized copper/rubrene interfaces as a function of temperature…
