Controlled Positioning of Carbon Nanotubes by Dielectrophoresis : Insights into the Solvent and Substrat Role

Benjamin Dwir, László Forró, Elyahou Kapon, Arnaud Magrez, Martial Duchamp

We demonstrate the ability to precisely control the deposition of a defined number of carbon nanotubes (CNTs) from solution onto microfabricated electrodes using dielectrophoresis. The solvation shelf around the CNTs, exhibiting a high dielectric constant ...

Dense arrays of pyramidal quantum dots with narrow linewidth photoluminescence spectra

Benjamin Dwir, Elyahou Kapon, Alok Rudra, Alessandro Surrente, Pascal Gallo, Marco Felici

Arrays of site-controlled, pyramidal InGaAs/GaAs quantum dots (QDs) grown by organo-metallic chemical vapour deposition with densities comparable to those of self-assembled QDs (5 x 109 cm(-2)) are demonstrated. The QDs exhibit high quality photoluminescen ...

Photonic-crystal microcavity laser with site-controlled quantum-wire active medium

Benjamin Dwir, Elyahou Kapon, Alok Rudra, Kirill Atlasov, Pascal Gallo, Milan Calic

Site-controlled quantum-wire photonic-crystal microcavity laser is experimentally demonstrated using optical pumping. The single-mode lasing and threshold are established based on the transient laser response, linewidth narrowing, and the details of the no ...

Effect of sidewall passivation in BCl3/N2 inductively coupled plasma etching of two-dimensional GaAs photonic crystals

Benjamin Dwir, Elyahou Kapon, Alok Rudra, Kirill Atlasov, Pascal Gallo

The effect of surface passivation in BCl3/N-2 inductively coupled plasma reactive-ion etching of GaAs-based photonic crystals (PhCs) was investigated. It is shown that sidewall passivation is crucial for achieving cylindrical, vertical PhC holes, where the ...
