Tailored nonmagnetic semiconductor-metal hybrid structures exhibit a large magnetoresistance effect in a homogeneous magnetic field. This is the so-called extraordinary magnetoresistance effect. Here, we study numerically the magnetoresistance of such hybr ...
Semiconductor-metal hybrid structures can show a large magnetoresistance effect, the extraordinary magnetoresistance (EMR) effect. In this work, we study theoretically the influence of the voltage probe configuration on the magnetoresistance of such hybrid ...
This paper reports on the preparation of silver/antimony-doped tin oxide (Ag/SnO2:Sb) hybrid interfaces using magnetron sputtering and their characterization. The influence of the Sri target composition (doping with 2 or 5% Sb) on the electrochemical and e ...
To perform a current sensing in capacitorless 1-transistor (IT) DRAMs on SOI, we have developed a sensing scheme with automatic reference generation. The reference current is generated by an adjustable current source. The electrical calibration of the refe ...
When it comes to designing active control disposals, sound pressure sensing is usually required. In the framework of active control of acoustic impedance, this work aims at conceiving a digital estimator that processes voltage and current measurement to co ...
We present a novel, inexpensive, and fast microimpedance tomography system for two-dimensional imaging of cell and tissue cultures. The system is based on four-electrode measurements using 16 planar microelectrodes (5 mum x 4 mm) integrated into a culture ...
JORDI (JOint Resistance DIstribution), a dedicated test facility for the measurement of contact resistance distribution in full-size, ITER type conductor terminations, has been successfully commissioned at CRPP. In contrast to earlier attempts, where the c ...
This thesis presents the fabrication and design of an impedance imaging sensor, and its application to monitoring in-vitro skin culture. Three-dimensional tissue cultures are becoming increasingly important in biological and medical research. There is, how ...
A semiconductor device for measuring ultra low currents down to the level of single electrons or low voltages comprises a first and a second voltage supply terminal (1, 2), an input terminal (3) for receiving an electrical current or being supplied with a ...
The four-point probe is used for the measurement of the resistivity of thin metal or semiconductor films. There is an interest in miniaturization of the probes to obtain higher surface sensitivity, an increased spatial resolution and less damage to the sam ...
