Growth of nanowire arrays from micron-feature templates

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

Template-Assisted Scalable Nanowire Networks

Anna Fontcuberta i Morral, Lucas Güniat, Gözde Tütüncüoglu, Martin George Friedl, Heidi Andrea Potts, Wonjong Kim, Mahdi Zamani, Vladimir Dubrovskii, Sara Marti Sanchez

Topological qubits based on Majorana Fermions have the potential to revolutionize the emerging field of quantum computing by making information processing significantly more robust to decoherence. Nanowires are a promising medium for hosting these kinds of ...

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

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