SPIE-Intl Soc Optical Eng2013

Growth mechanisms and process window for InAs V-shaped nanoscale membranes on Si[001]

Anna Fontcuberta i Morral, Martin Heiss, Esther Alarcon Llado, Gözde Tütüncüoglu, Eleonora Russo, Sonia Conesa Boj, Anna Dalmau Mallorquí, Ignasi Canales Mundet

Organized growth of high aspect-ratio nanostructures such as membranes is interesting for opto-electronic and energy harvesting applications. Recently, we reported a new form of InAs nano-membranes grown on Si substrates with enhanced light scattering prop ...

Enhanced second harmonic generation from InAs nano-wing structures on silicon

Anna Fontcuberta i Morral, Eleonora Russo, Anna Dalmau Mallorquí, Ignasi Canales Mundet

We demonstrate morphology-dependent second-harmonic generation (SHG) from InAs V-shaped nanomembranes. We show SHG correlation with the nano-wing shape and size, experimentally quantify the SHG efficiency, and demonstrate a maximum SHG enhancement of about ...

Vertical "III-V" V-Shaped Nanomembranes Epitaxially Grown on a Patterned Si[001] Substrate and Their Enhanced Light Scattering

Anna Fontcuberta i Morral, Martin Heiss, Eleonora Russo, Sonia Conesa Boj, Anna Dalmau Mallorquí, Ludovit Pavel Zweifel

We report on a new form of III-IV compound semiconductor nanostructures growing epitaxially as vertical V-shaped nanomembranes on Si(001) and study their light-scattering properties. Precise position control of the InAs nanostructures in regular arrays is ...

Effect of the pn junction engineering on Si microwire-array solar cells

Anna Fontcuberta i Morral, Anna Dalmau Mallorquí, Franz Michael Epple

We report on the impact of the doping concentration design on the performance of silicon microwire arrays as photovoltaic devices. We have fabricated arrays with different p- and n-doping profiles and thicknesses, obtaining mean efficiencies as high as 9.7 ...

Development and characterization of EIS structures based on SiO2 micropillars and pores before and after their functionalization with phosphonate films

Anna Fontcuberta i Morral, Anna Dalmau Mallorquí

In this work electrolyte insulator semiconductor (EIS) structures based on lithographically fabricated Si SiO2 micropillars and pores are studied. The samples are characterized by means of impedance spectroscopy (IS) and they are compared to samples with a ...
