Impact of Sn/Zn ratio on the gate bias and temperature-induced instability of Zn-In-Sn-O thin film transistors
We investigated the effect of the Sn/Zn ratio in the amorphous Zn-In-Sn-O (ZITO) system on the gate voltage stress-induced stability of the resulting thin film transistors (TFTs). The device stability...

Effects of hydration levels on the bandwidth of microwave resonant absorption induced by confined acoustic vibrations
We found the hydration levels on the capsid surface of viruses can affect the bandwidth of microwave resonant absorption (MRA) induced by the confined acoustic vibrations (CAV). By decreasing the pH v...

We present a multichannel cardiac magnetic field imaging system built in Fribourg from optical double-resonance Cs vapor magnetometers. It consists of 25 individual sensors designed to record magnetic field maps of the beating human heart by simultaneous measurements on a grid of 19 points over the chest. The system is operated as an array of second order gradiometers using sophisticated digitally controlled feedback loops. ©2009 American Institute of Physics
