Kurzweil : "Overcoming transistor miniaturization limits due to ‘quantum tunneling’

Kurzweil : "Overcoming transistor miniaturization limits due to ‘quantum tunneling’ | Ce monde à inventer ! | Scoop.it

Kurzweil 07/07/18 : "A team of researchers at Columbia Engineering and associates* have synthesized a molecule that could overcome a major physical limit to miniaturizing computer transistors at the nanometer scale (under about 3 nanometers) — caused by “leakage current.” […].

 

The researchers synthesized the first molecule** capable of insulating (preventing electron flow) at the nanometer scale more effectively than a vacuum barrier (the traditional approach). The molecule bridges the nanometer gap between two metal electrodes...

Kurzweil : "First transistors made entirely of nanocrystal ‘inks’ in simplified process | Ce monde à inventer ! | Scoop.it
Kurzweil 07/04/16 : "University of Pennsylvania engineers have developed a simplified new approach for making transistors by sequentially depositing their components in the form of liquid nanocrystal “inks.” The new process open the door for transistors and other electronic components to be built into flexible or wearable applications [...]. The researchers’ nanocrystal-based field effect transistors were patterned onto flexible plastic backings using spin coating, but could eventually be constructed by additive manufacturing systems, like 3D printers...

Kurzweil : "Physicists at The University of Texas at Austin have had the first-ever glimpse into what happens inside an atomically thin semiconductor device. In doing so, they discovered that a transistor may be possible within a space so small (the edge) that it’s effectively one-dimensional...
