Thickness effect and mechanical tuning behavior such as strain engineering in thin-film ferroelectrics have been extensively studied widely used to tailor the ferroelectric properties. However, this is never case freestanding single crystals, conclusions from thin films cannot be duplicated because of differences nature boundary conditions single-crystal ferroelectrics. Here, using situ biasing transmission electron microscopy, we thickness-dependent domain switching predicted trend...
The development of a tunable, multiple degree freedom (MDOF) electromechanical Helmholtz resonator (EMHR) is presented. An EMHR consists an orifice, backing cavity, and compliant piezoelectric composite diaphragm. Electromechanical tuning the acoustic impedance achieved via passive electrical networks shunted across piezoceramic. For resistive capacitive loads, 2DOF system possessing one mechanical DOF. When inductive ladder are employed, DOF added. dynamics multi-energy domain modeled using...
A novel multiparametric biosensor system based on living cells will be presented. The includes two biosensing techniques a single device: resonant frequency measurements and electric cell-substrate impedance sensing (ECIS). sensor is the innovative use of upper electrode quartz crystal microbalance (QCM) resonator as working for ECIS technique. QCM acoustic wave consists thin AT-cut substrate with gold electrodes opposite sides. For integration technique semicircular counter was fabricated...
Single-phase (00l)-oriented Bi2Te3 topological insulator thin films have been deposited on (111)-oriented ferroelectric 0.71Pb(Mg1/3Nb2/3)O3–0.29PbTiO3 (PMN–PT) single-crystal substrates. Taking advantage of the nonvolatile polarization charges induced by direction switching PMN–PT substrates at room temperature, carrier density, Fermi level, magnetoconductance, conductance channel, phase coherence length, and quantum corrections to can be in situ modulated a reversible manner. Specifically,...

Strongly correlated perovskite transition-metal oxides have received considerable attention due to their intriguing physical properties, including a metal-insulator transition that can be used in devices. Key questions remain, though, whether in-plane tensile strain helps or hinders the transition. This study uses both static and dynamic lattice manipulate transport properties of NdNiO${}_{3}$ films systematically. The electric-field-tunable ferroelastic/piezoelectric approach not only...
