摘要： A pyroelectric generator may be included in the same semiconductor device as a radio frequency (RF) switch (e.g., a phase-change material (PCM) RF switch and/or other types of RF switch). The pyroelectric generator includes a pyroelectric material layer between two electrodes. The pyroelectric generator is configured to scavenge thermal energy that is generated during the operation of the RF switch, and to convert the thermal energy into electrical energy that may be stored and reused.

摘要： When a magnetic field is applied parallel to a layer of thermoelectric material, and an electric field is applied perpendicular to the layer, electrical carriers in the layer follow cyclotron orbits interrupted by one of the layer's surfaces. These interrupted orbits produce a drift current along the layer and perpendicular to both fields. Therefore, the inputs are a magnetic field and an electric field, and the output is a current. The phenomenon differs from the classical Hall Effect in which the inputs are a magnetic field and a current and the output is a voltage. The output current produces electrical energy which can be used immediately, stored for later consumption, converted to another form or transmitted to another location. Layers can be stacked, each layer of the stack mutually reinforcing the electrical field in the adjacent stack layers. Stacked layers can be connected in series or parallel.

摘要： Methods for producing ferroelectric device are described. A method includes positioning an organic polymeric ferroelectric layer between two conductive materials to form a stack. The stack can be subjected to a 2-step heat treating process. The first heat treating step transforms the organic polymeric ferroelectric precursor to a ferroelectric material having ferroelectric hysteresis properties, and the second heat treating step densities the ferroelectric material to obtain the ferroelectric device. The thin film ferroelectric device can include a thin film ferroelectric capacitor, a thin film ferroelectric transistor, or a thin film ferroelectric diode.
