News and events of Philip Feng's Research Group
The cover of Applied Physics Letters' first issue of 2022 features the work of IMG members Dr. Jaesung Lee and Prof. Philip Feng and their collaborator. In the article, “Design of strongly nonlinear graphene nanoelectromechanical systems in quantum regime,” the authors show that atomically thin nonlinear nanoelectromechanical systems (NEMS) can offer sufficient anharmonicity for quantum NEMS to behave like artificial atoms, thus feasible to enable qubit devices with much smaller footprints than today’s qubit hardware.
The recent article titled, "Resolving Mechanical Properties and Morphology Evolution of Free-Standing Ferroelectric Hf0.5Zr0.5O2" targets the accurate extraction of Young's modulus, built-in stress, and crystal morphology change upon release of hafnia-zirconia thin films. Hafnia-zirconia is uniquely positioned to revolutionize nanoscale transducers, allowing for nanomechanical sensors and actuators to be monolithically integrated within CMOS.
