New Diodes (Quantum) Tunnel Their Way To Improved Electronics
Researchers at Oregon State University develop cutting edge metal-insulator-metal diodes, harnessing quantum tunneling of electrons to increase performance of electronics.
Nano Silicon Samurai?
Welcome to one of our guest columns, where active researchers can share their views on topics relevant to materials science. Professor Geoffrey Ozin from the University of Toronto tells us what he thinks about nanoscale silicon and its future. One thing that has...
Edible Electronics: Purely Biocompatible Electrical Devices
Scientists from the University of Linz engage in developing electronics that can simply be thrown onto the compost heap or, if in a pinch, could even be eaten!
Piezotronic Logic Gates Take the Strain
US scientists have developed the first examples of logic gates (NAND, NOR and XOR gates) that can be switched simply by bending the substrate.
Porous silicon nanoneedles for barcodes and other applications
Researchers at the University of Texas have fabricated biodegradable, nanobarcodes of silicon. The porosity of the silicon structures enables their applications in bioengineering, energy storage, and drug delivery systems.
Dimensionally Different: Complex Patterned Photoresists
Scientists in the USA have exploited all three dimensions of patterned photoresists, to make complex components using just one template.
