Energy self-sufficient microsystems equipped with a micro energy harvester also need an adequate energy storage device with a high energy density to guarantee reliable and long-lasting operation. A combined system which can tap and store ambient energy as well as deliver constant and continuous electrical power is desirable. Therefore we have developed a novel fuel cell type accumulator with an integrated...
As Flash memories are approaching their ultimate scaling limit, reversible resistance switching attracts considerable interest because of its potential for high density non volatile memory devices. Resistive switching phenomena have been reported in many transition metal oxide films such as TiO2 or MO. This work investigates the feasibility of emerging resistive- switching devices with NiO active...
Resistance switching is an interesting alternative to conventional charge storage devices for future high density storage media. Cu/CuTCNQ(300 nm)/Al memory structures with pad size ranging from 1000 down to 150 ??m were carefully studied to apprehend their switching behavior. Electrical testing revealed bipolar resistive switching and a shrink of the memory window as the pad-size decreased. Current...
The performances of BAW resonators depend on their size and shape. A model is presented that describes this dependence. The electrical behavior of the resonator is subdivided into two parts. The ideal resonator, composed of the piezoelectric layer sandwiched between two electrodes, provides an ideal response while parasitic elements are degrading it. The model deals with the performances of the ideal...
Conventional memories approaching their scaling limit, reversible resistance switching effects attract considerable attention because of the potential for high density non volatile memory devices. These resistive switching phenomena have been reported in many simple transition metal oxide films such as TiO2 or NiO deposited by standard sputtering techniques. This paper is investigating the feasibility...
