Nonvolatile ferroelectric field effect transistor based on a vanadium dioxide nanowire with large on- and off-field resistance switching
Literature Information
We fabricate a ferroelectric field effect transistor (FeFET) based on a semiconducting vanadium dioxide (VO2) nanowire (NW), and we investigate its electron transport characteristics modulated by the ferroelectric effects. The transistor consists of a single VO2 NW as the channel and a ferroelectric Pb(Zr0.52Ti0.48)O3 (PZT) thin film as the dielectric gate. The conductance of the VO2 NW channel is found to be feasibly modulated by the ferroelectric gate with an 85% resistance change under the gate voltage of 18 V (at an applied field of about 0.75 MV cm−1). The electron transport property of the device can be controlled by the remnant polarization of the PZT layer due to the nonvolatile property of the ferroelectric gate, with an off-field change of channel resistance up to 50%. Moreover, multiple resistive states can be achieved by sweeping gate voltage across the device appropriately. These results demonstrate that ferroelectric gate modulation is an efficient tool to regulate the electron transport properties of the VO2 NW, and the VO2-NW-FeFET has potential applications in nonvolatile and low-power consumption devices.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
