Friction Between Single Layer Graphene And An Atomic Force Microscope Tip


A technical paper titled “Dynamically tuning friction at the graphene interface using the field effect” was published by researchers at University of Illinois Urbana-Champaign and University of California Irvine. Abstract: "Dynamically controlling friction in micro- and nanoscale devices is possible using applied electrical bias between contacting surfaces, but this can also induce unwant... » read more

Protecting Power Management Circuits Against Trojan Attacks


A technical paper titled “Hardware Trojans in Power Conversion Circuits” was published by researchers at UC Davis. Abstract: "This report investigates the potential impact of a Trojan attack on power conversion circuits, specifically a switching signal attack designed to trigger a locking of the pulse width modulation (PWM) signal that goes to a power field-effect transistor (FET). The fi... » read more

Taming NBTI To Improve Device Reliability


Negative-bias temperature instability is a growing issue at the most advanced process nodes, but it also has proven extremely difficult to tame using conventional approaches. That finally may be starting to change. NBTI is an aging mechanism in field-effect transistors that leads to a change of the characteristic curves of a transistor during operation. The result can be a drift toward unint... » read more

Robotic plants In 2012, the European Commission launched the so-called Plantoid project. In the project, researchers hope to devise synthetic robotic plants. Inspired by plant roots, the robots could be used for soil monitoring and other applications. The group is devising so-called artifacts. These components resemble plants and plant roots. The new technologies expected to result from the... » read more

Manufacturing Bits: Jan. 6


Vertical SiC chips for electric cars Silicon carbide (SiC) is a promising material for power electronics. The material has a high breakdown voltage, high operating temperatures and a superior thermal conductivity. At the recent 2014 IEEE International Electron Devices Meeting (IEDM) in San Francisco, Toyota, the National Institute of Advanced Industrial Science and Technology (AIST) and the... » read more

Manufacturing Bits: Oct. 21


Peanut butter and chocolate TEMs Lawrence Livermore National Laboratory, Johns Hopkins University and the National Institute of Standards and Technology (NIST) have developed a new microscopy technology that combines two types of key measurements. The technology, dubbed the dynamic transmission electron microscope (DTEM), captures information about both temperature and the crystal structure... » read more
