Ana Isabel Bento Rovisco

Advanced Functional Materials for Micro and Nanotechnologies
Assistant Researcher
2.21 13743


Ana Rovisco completed the PhD in Nanotechnologies and Nanosciences in 2019/12/20 by NOVA School of Science and Technology (FCT-NOVA), NOVA University Lisbon (at Department of Materials Science and i3N/CENIMAT) and the Integrated Master in Physics Engineering in 2012 by the same University (at Department of Physics). 

She is currently assistant researcher at CENIMAT, where she is a researcher since 2013. Since 2014 she is also lab assistant of several courses (>5) related with nanofabrication and materials characterization in the same university. 

She published 15 articles in peer-reviewed international journals (h-index=8, as July 2021), 2 book chapter and 2 conference paper. She is currently topic editor on Chemosensors (MDPI) and reviewed papers for >10 international journals. She has more than 50 communications in national and international conferences and seminars.  Participates and/or participated as researcher in > 10 international and national projects. 

Currently, the main focus of her work is the synthesis, characterization and application of metal oxide nanostructures. She is particularly interested in electrical characterization of single nanowires, resorting to e-beam lithography and gas injection tools. In terms of applications, her main focus are electronic devices (FETs and memories), energy harvesting devices and photocatalysis.

Main scientific interests: Solution-based synthesis of oxide nanostructures; Nanolithography (EBL) and nanofabrication; Nanodevices; Flexible and transparent technology; Oxide thin film transistors.

Materials characterization techniques: XRD, SEM/EDS and electrical characterization of devices/circuits.
