Research Bits: September 11


Combining digital and analog Researchers from École Polytechnique Fédérale de Lausanne (EPFL) propose integrating 2D semiconductors with ferroelectric materials for joint digital and analog information processing, which could improve energy efficiency and support new functionality. The device uses a 2D negative-capacitance tungsten diselenide/tin diselenide tunnel FET (TFET), which consu... » read more

TFETs Cut Sub-Threshold Swing


One of the main obstacles to continued transistor scaling is power consumption. As gate length decreases, the sub-threshold swing (SS) — the gate voltage required to change the drain current by one order of magnitude — increases. As Qin Zhang, Wei Zhao, and Alan Seabaugh of Notre Dame explained in 2006, SS faces a theoretical minimum of 60 mV/decade at room temperature in conventional MO... » read more
