Spit power According to researchers at Penn State who’ve created a saliva-powered micro-sized microbial fuel cell, their invention can produce minute amounts of energy sufficient to run on-chip applications. Researcher Justine E. Mink has been credited with the idea as she was thinking about sensors for such things as glucose monitoring for diabetics and wondered if a mini microbial fuel ... » read more

Outperforming copper Carbon nanotube-based fibers invented at Rice University have greater capacity to carry electrical current than copper cables of the same mass -- on a pound-per-pound basis -- according to new research. While individual nanotubes are capable of transmitting nearly 1,000 times more current than copper, the same tubes coalesced into a fiber using other technologies fail l... » read more

The List Of Unknowns Grows After Silicon
By Katherine Derbyshire - 07 Feb, 2014 - Comments: 3

As discussed earlier in this series, most proposed alternative channel schemes depend on germanium channels for pMOS transistors, and InGaAs channels for nMOS transistors. Of the two materials, InGaAs poses by far the more difficult integration challenges. Germanium has been present in advanced silicon CMOS fabs for several technology generations, having been introduced used in strained silicon... » read more

Implantable TFETs At the recent IEEE International Electron Devices Meeting (IEDM) in Washington, D.C., a number of companies, R&D organizations and universities described new breakthroughs in perhaps the next big thing in semiconductors--the tunnel field-effect transistor (TFET). Aimed for the 5nm node, TFETs are steep sub-threshold slope transistors that can scale the supply voltages bel... » read more

Low-power tunneling transistor to enable high-performance devices To make fast and low-power computing devices possible for energy-constrained applications such as smart sensor networks, implantable medical electronics and ultra-mobile computing, a new type of transistor is needed. To this end, researchers at Penn State, the National Institute of Standards and Technology and specialty wafer fo... » read more

Flexible, organic solar cells Work by a team of chemical engineers at Penn State and Rice University may lead to a new class of inexpensive organic solar cells. If solar cells could be made as easily as posters or newspapers are printed, sheets of organic solar cells could be made, representing a fundamental shift in the way solar cells are made, the researchers said. Today, most solar c... » read more

What Comes After FinFETs?
By Ed Sperling - 16 Aug, 2012 - Comments: 0

By Mark LaPedus The semiconductor industry is currently making a major transition from conventional planar transistors to finFETs starting at 22nm. The question is what’s next? In the lab, IBM, Intel and others have demonstrated the ability to scale finFETs down to 5nm or so. If or when finFETs runs out of steam, there are no less than 18 different next-generation candidates that could o... » read more
