Growth of nanowire arrays from micron-feature templates

Anna Fontcuberta i Morral, Gaëtan Bernard, Martin George Friedl, William Craig Carter, Dmitry Mikulik, Lea Ghisalberti, Wonjong Kim, Pablo Romero Gómez, Christian André Jürgensen

Here, we present a two-step annealing procedure to imprint nanofeatures on SiO2 starting from metallic microfeatures. The first annealing transforms the microfeatures into gold nanoparticles and the second imprints these nanoparticles into the SiO2 layer w ...

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 ...

Fundamental aspects to localize self-catalyzed III-V nanowires on silicon

Anna Fontcuberta i Morral, Jelena Vukajlovic Plestina, Martin George Friedl, Heidi Andrea Potts, William Craig Carter, Lea Ghisalberti, Wonjong Kim, Vladimir Dubrovskii

III-V semiconductor nanowires deterministically placed on top of silicon electronic platform would open many avenues in silicon-based photonics, quantum technologies and energy harvesting. For this to become a reality, gold-free site-selected growth is nec ...

Bi-stability of contact angle and its role in tuning the morphology of self-assisted GaAs nanowires

Anna Fontcuberta i Morral, Gözde Tütüncüoglu, Jean-Baptiste Leran, Lucas Güniat, Jelena Vukajlovic Plestina, Martin George Friedl, Heidi Andrea Potts, Luca Francaviglia, Wonjong Kim, Vladimir Dubrovskii

We demonstrate the existence of two stable contact angles for the gallium droplet on top of self-assisted GaAs nanowires grown by MBE on patterned silicon substrates. Contact angle around 130 degrees fosters a continuous increase in the nanowire radius, wh ...
