In this work, we present an electronic board used for conducting Interpenetrating Polymer Networks (IPNs) which can be used as sensors and/or actuators. The first prototype allows the user to generate custom signals for actuation purposes (steps, sine, triangle…). It can also record the deformations applied to the device by reading the voltage between the two electrodes. However, the voltage required...
By using sidewall electrode technology, both record small functional TiO2 selection device (1 × 5 nm2) and HfO2 based RRAM device (1 × 3 nm2) were for the first time successfully demonstrated in this work, improving the understanding of the switching mechanism in an ultra-small, functional resistive random access memory (RRAM) device. The tunneling based low temperature back-end selection devices...
Large magnetoresistance (MR) in non-magnetic semiconductors, especially silicon, the mainstream semiconductor in information technology, attracts a lot of attentions because of its interesting physics and broad applications [1-6]. One pathway to achieve large MR is to utilize the resistance transition resulted from the rectification characteristics of diodes, which is called as diode-assisted MR....
Silicon based Flash memories is the mainstream of the current random access memory (RAM) technique. However, it is close to reach its physical limit for miniaturization. So a few kinds of new RAMs have been proposed such as magnetic RAM (MRAM) [1], phase-change RAM [2] and resistive RAM (RRAM) [3]. RRAM is investigated due to its potential of miniaturization and ultrahigh operation speed. An RRAM...
A sidewall electrode technology was successfully developed for the first time in this study, improving the understanding of the working mechanism in an ultra small, functional HfO2-based resistive random access memory (RRAM) device (< 1 × 3 nm2). This technology exhibits potential for application in atomic-scale memories. The 1 × 3 nm2 RRAM device exhibited an excellent performance, featuring a...
The general operation of a piezoelectric ultrasonic actuator is to convert the cyclic motion of the piezoelectric plate to a linear motion at the rotor or slider. The conventional piezoelectric ultrasonic actuator has two symmetric exciter electrodes on the front surface and each electrode covers one half of the front surface. The rear surface has only one electrode that severs as a common drain....
The assembly of a single carbon nanocoil on the tip of an atomic force microscope probe has been demonstrated by utilizing dielectrophoresis in an isopropyl alcohol solution. The nanocoil adheres to the probe tip where the maximum electrical field exists. Its orientation due to the relative position between the probe tip and the dielectrophoresis electrode has been investigated. The capillary effect...
Microscopical investigation of leakage behaviors of Hf-based high-k gate stacks was achieved by means of electron-beam-induced current (EBIC) method. Carrier separated EBIC measurement has found that in non-stressed samples, hole conduction in pMOS is significantly enhanced by trap-assisted tunneling, while electron conduction in nMOS is independent of traps. The transport mechanisms of electron and...
The authors show that the propagation of the gastric activities in the stomach can be detected from abdominally recorded EGGs (electrogastrograms). The conventional measurement method is not adequate for detecting the propagation. The stomach must be carefully localized before the measurement. The electrodes should be attached on the abdomen along the longitudinal axis of the stomach. Phase shifts...
In an effort to better understand the process of charge transport in extended chain aromatic hetero-cyclic polymers we have made detailed studies of d.c. conduction in one such rigid rod polymer, viz. poly(p-phenylene benzobisthiazole) or PPBT *** Two types of transient currents have been measured. One of these is the gradual decay of current over a long period of time in a PPBT sample exposed to...
