Kinetic control of ferroelectricity in ultrathin epitaxial Barium Titanate capacitors
Harish Kumarasubramanian, Prasanna Venkat Ravindran, Ting-Ran Liu +11
Ferroelectricity is characterized by the presence of spontaneous and switchable macroscopic polarization. Scaling limits of ferroelectricity have been of both fundamental and techn…
Growth of VO2-ZnS Thin Film Cavity for Adaptive Thermal Emission
Raymond Yu, Bo K. Shrewsbury, Claire Wu +4
Low-weight, passive, thermal-adaptive radiation technologies are needed to maintain an operable temperature for spacecraft while they experience various energy fluxes. In this stud…
