Figure 3
Setup for the application of voltage pulse sequences to FE test devices. The sample is glued on a conducting metal holder that is connected to an oscilloscope for the measurement of the FE switching current. A W needle establishes the electrical contact to a metallic top electrode (see also the inset). In order to change between different top electrodes, the needle can remotely lifted up and the sample moved relatively to the needle with the x, y stages. The plastic needle holder movement is remotely operated and its lowering motion is damped with an induction coil. |
