Making flexible carbon nanotube circuits more reliable and efficient Engineers would love to create flexible electronic devices, such as e-readers that could be folded to fit into a pocket with one such approach involving designing circuits based on electronic fibers known as carbon nanotubes (CNTs) instead of rigid silicon chips -- but reliability is essential. Given that most silicon chip... » read more

Self-completing programs Since he was a graduate student, Armando Solar-Lezama, an associate professor in MIT’s Department of Electrical Engineering and Computer Science, has been working on a programming language called Sketch -- which allows programmers to simply omit some of the computational details of their code – and then automatically fills in the gaps. If it’s fleshed out and ... » read more

MoS2 FETs Two-dimensional materials are gaining steam in the R&D labs. The 2D materials include graphene, boron nitride (BN) and the transition-metal dichalcogenides (TMDs). One TMD, molybdenum diselenide (MoS2), is an attractive material for use in future field-effect transistors (FETs). MoS2 has several properties, including a non-zero band gap, atomic scale thickness and pristine int... » read more

Lasers From Nano Wires A few weeks ago, Semiconductor Engineering published a special report about silicon photonics and concentrated on the integration of the laser onto the silicon surface. Growing III-V materials on silicon is problematic because of the lattice mismatch, but researchers at the Technische Universität München (TUM) may have found a way around that problem. Thread-like semic... » read more

Thermal emitter improves solar cell efficiency Stanford University scientists have created a heat-resistant thermal emitter -- an element used in specialized solar cells -- that could significantly improve the efficiency of the cells. The heat-resistant thermal emitter is designed to convert heat from the sun into infrared light that can be absorbed by solar cells to make electricity – a tec... » read more

The next big thing in particle accelerators Stanford University engineers have helped create what may be the next big thing in particle accelerators – and it fits on a fingertip. In a project that included scientists from the U.S. Department of Energy’s SLAC National Accelerator Laboratory, a linear accelerator two miles long, accelerators energized charged particles to accomplish a ran... » read more

Generating electricity from sewage Stanford University researchers have come up with a new way to generate electricity from sewage using naturally-occurring “wired microbes” as mini power plants, producing electricity as they digest plant and animal waste. Calling their invention a ‘microbial battery,’ the researchers hope one day it will be used in places such as sewage treatment p... » read more
