摘要： Current techniques for measuring chemical expansion in thin film structures are too slow, too imprecise, or require synchrotrons. In contrast, nanoscale electrochemomechanical spectroscopy (NECS) can be used to make nanoscale measurements at time scales of seconds with simple contact or non-contact sensors. In a NECS measurement, a sample, such as thin-film oxide structure, is subjected to a temporally modulated stimulus, such as a sinusoidally alternating voltage. The stimulus causes the sample to expand, contract, deflect, or otherwise deform. A sensor, such as a contact probe or optical sensor, produces an electrical signal in response to this deformation that is correlated with the temporal modulation of the stimulus. Because the stimulus and deformation are correlated, the temporal modulation of the stimulus can be used to filter the deformation signal produced by the sensor, producing a precise, sensitive measurement of the deformation.

摘要： Thin-film composite materials with nanometer-scale grains comprise a thin-film layer that includes at least an electronic and an ionic conductor, and can be porous and/or resistant to redox-degradation. The thin-film composite materials can be formed by simultaneous co-deposition of at least an electronic and an ionic conductor onto a substrate using physical vapor deposition methods. Sacrificial materials can be co-deposited with the electronic and ionic conductors and subsequently removed from the thin-film layer to form a network of pores in the thin-film layer, that is, a porous thin-film composite material. A solid oxide fuel cell comprises an anode, an electrolyte and a cathode, wherein the anode and cathode are independently a thin-film composite material and the electrolyte is a thin-film material. Particularly, redox-degradation resistant thin-film composite materials can be used both as anodic and cathodic electrodes, which allows fabrication of fuel cell stacks with symmetric thermo-mechanical properties, thereby increasing mechanical stability. The nanometer-scale grain size and intimate phase mixing in these composites leads to increased reaction kinetics, and therefore is expected to yield increased power output from fuel cell stacks employing these thin-film composite materials.

摘要： An optoelectronic memristor includes a first electrode, a second electrode, and a solid electrolyte in between that is in electrical communication with the first electrode and the second electrode. The solid electrolyte has an electronic conductivity of about 10−10 Siemens/cm to about 10−4 Siemens/cm at room temperature. The first electrode, and optionally the second electrode, can be optically transparent at a specific wavelength and/or a wavelength range. A direct current (DC) voltage source is employed to apply an electric field across the solid electrolyte, which induces a spatial redistribution of ionic defects in the solid electrolyte. In turn, this causes a change in electrical resistance of the solid electrolyte. The application of the electric field can also cause a change in an optical property of the solid electrolyte at the specific wavelength, and/or at the wavelength range (or a portion thereof).

摘要： Reconfigurable, active optical components can flexibly manipulate light. One example of these components is an electro-chemo-optical device that utilizes a metal oxide film with a complex refractive index that varies as a function of an oxygen vacancy concentration. The optical device may include a metal oxide film, a first electrode, and a second electrode. The first electrode and the second electrode may be used to supply a bias voltage to induce a change in the oxygen vacancy concentration in order to change the optical properties (absorbance, transmittance, and/or reflectance) of the optical device. The magnitude and spatial distribution of the oxygen vacancy concentration may be altered to affect the optical properties of the optical device. In some designs, the optical device may also include an ionic conductor and oxygen source to supply/receive oxygen ions to/from the metal oxide film.
