Highly sensitive piezotronic pressure sensors based on undoped GaAs nanowire ensembles

Anna Fontcuberta i Morral, Jelena Vukajlovic Plestina, Wonjong Kim

Semiconducting piezoelectric materials have attracted considerable interest due to their central role in the emerging field of piezotronics, where the development of a piezo-potential in response to stress or strain can be used to tune the band structure o ...

Quantitative Nanoscale Absorption Mapping: A Novel Technique To Probe Optical Absorption of Two-Dimensional Materials

Andras Kis, Anna Fontcuberta i Morral, Dumitru Dumcenco, Luca Francaviglia, Marco Negri

Two-dimensional semiconductors, in particular transition metal dichalcogenides and related heterostructures, have gained increasing interest as they constitute potential new building blocks for the next generation of electronic and optoelectronic applicati ...

Layer transfer of epitaxial layers and thin films obtained by van der waals growth initiation

Anna Fontcuberta i Morral, Andrea Giunto, Rajrupa Paul

A thin film grown on a substrate to which the attractive forces are of lower strength than covalent, metallic and/or ionic bonds can be detached from the substrate without the need of a Smart-cut type of process, e.g. without the need of ion implantation. ...

Unveiling Temperature-Dependent Scattering Mechanisms in Semiconductor Nanowires Using Optical-Pump Terahertz-Probe Spectroscopy

Anna Fontcuberta i Morral, Gözde Tütüncüoglu, Francesca Amaduzzi, Heidi Andrea Potts

Optical-pump terahertz-prohe (OPTP) spectroscopy is a powerful, non-contact tool for extracting the electrical conductivity within a material. In this work, we show how OPTP spectroscopy can he used to extract the temperature-dependent electron mobility an ...
