Power/Performance Bits: Oct. 11

Getting to 1nm Researchers at the Lawrence Berkeley National Laboratory, UC Berkeley, University of Texas at Dallas, and Stanford University created a transistor with a working 1nm gate from carbon nanotubes and molybdenum disulfide (MoS2). "The semiconductor industry has long assumed that any gate below 5 nanometers wouldn't work, so anything below that was not even considered," said fir... » read more

Self-organizing circuits Researchers studying the behavior of nanoscale materials at the Department of Energy's Oak Ridge National Laboratory discovered that due an unusual feature of certain complex oxides called phase separation, individual nanoscale regions can behave as self-organized circuit elements, which could support new multifunctional types of computing architectures. "Within a... » read more

Crystal database The University of California at San Diego and Lawrence Berkeley National Laboratory have created an open-source database of elemental crystal surfaces and shapes. The database, called Crystalium, is a new and expanding set of information about various crystals. The database can help researchers design new materials for various applications, such as batteries, catalytic conv... » read more

Hiding wires from the sun There's a problem with most solar cells: the electricity-carrying metal wire grid on top prevents sunlight from reaching the semiconductor below. A team from Stanford University tackled this problem, discovering a way to hide the reflective upper contact and funnel light directly to the semiconductor below. For the study, the researchers placed a 16-nanometer-thi... » read more

Self-Assembling Nano Films Applying thin films with uniformity has always been an engineering challenge, but as feature sizes shrink the problem become even more pronounced. But a new approach developed by Lawrence Berkeley National Labs’ Materials Science Division could end up simplifying this process. The new approach used chloroform as an annealing solvent to create self-assembling arr... » 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

Optical Metamaterial with a Refractive Index of Zero Most of the time we hear about the need for coherent light sources, such as those produced by lasers, but there may be equal promise looking in the other direction. Quantum processors promise to be many times faster and more powerful than today’s supercomputers, but to get to that point they will need fast and efficient multi-directiona... » read more

Toothpick Fab Tools NASA's Goddard Space Flight Center in Greenbelt, Md. has developed a specialized atomic layer deposition (ALD) system and a "virtual toothpick" to enable ultra-thin films on chips and systems. NASA has built an ALD reactor chamber, which measures three inches in diameter and two feet in length. The system can deposit films inside pores and cavities, giving ALD the abilit... » read more

Fishy Robots National University of Singapore (NUS) has developed a robotic fish that mimics the movements of a carp—a technology that could pave the way for more efficient autonomous underwater vehicles. This robot is classified as an autonomous underwater vehicle (AUV). Applications include military, pipeline leakage detection, and the laying of communication cable. The robot could be u... » read more
