Three-Dimensionally Enlarged Photoelectrodes by a Protogenetic Inclusion of Vertically Aligned Carbon Nanotubes into CH3NH3PbBr3 Single Crystals

László Forró, Endre Horvath, Andrzej Sienkiewicz, Xavier François Mettan, Bálint Náfrádi, Márton Kollár, Pavao Roko Andricevic, Klara Hernadi

We demonstrate that single crystals of methylammonium lead bromide (MAPbBr(3)) could be grown directly on vertically aligned carbon nanotube (VACNT) forests. The fast-growing MAPbBr3 single crystals engulfed the protogenetic inclusions in the form of indiv ...

Carbon nanotube gas sensor array for multiplex analyte discrimination

Montserrat Fernandez-Bolanos Badia, Hoël Maxime Guérin, Elizabeth Buitrago Godinez

The lack of selectivity toward a particular analyte has always been the primary concern regarding CNT-based gas sensors. For that reason, in here we present a gas discrimination strategy that focuses on the electrode-CNT junction. The junction is shown to ...

In-situ grown horizontal carbon nanotube membrane

Mihai Adrian Ionescu, Dimitrios Tsamados, Hoël Maxime Guérin

We present the successful fabrication of horizontally grown and dense carbon nanotube (CNT) membranes in situ. A TiN/Al2O3/TiN stack is first patterned to be employed as a support for the CNT growth. Iron is then evaporated with a 45 degrees tilt angle on ...
