The Physics Of Ferroelectrics


The physics of ferroelectric materials is a large topic — too large for comprehensive coverage in a single article. While researching my recent article on negative capacitance, I found a number of papers that might be of interest to readers seeking more depth. Researchers in Japan used ferroelectric BiFeO3 to control the behavior of CaMnO3, a Mott insulator. Changing the polarization of th... » read more

Zeroing In On Biological Computing


Artificial spiking neural networks need to replicate both excitatory and inhibitory biological neurons in order to emulate the neural activation patterns seen in biological brains. Doing this with CMOS-based designs is challenging because of the large circuit footprint required. However, researchers at HP Labs observed that one biologically plausible model, the Hodgkins-Huxley model, is math... » read more
