Title
Low Power Nanoscale Switching of VO<inf>2</inf>using Carbon Nanotube Heaters
Abstract
Vanadium dioxide (VO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) is attractive for a variety of applications in optics and electronics, due to its abrupt insulator-metal transition (IMT) with >10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> × change in resistance near room temperature. Use of VO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> in devices will require low power switching, with knowledge of the transition mechanism and behaviour down to nanoscale dimensions. To address this challenge, we use metallic carbon nanotubes (CNTs) with diameter ~1 nm [1] to probe nanoscale IMT in VO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> for the first time. We find that a single CNT locally switches the VO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> at less than half the voltage and power otherwise required. Furthermore, to understand the nanoscale IMT we use scanning probe microscopy (SPM) techniques to study devices during operation.
