IBM/Samsung/GloFo consortium has already demonstrated a 7nm SiGe chip. IBM is also heavily researching carbon-nanotubes transistors, but I doubt we'll see those before 5nm, or even later (so potentially 2025+). http://arstechnica.com/gadgets/2015/07/ibm-unveils-industrys-first-7nm-chip-moving-beyond-silicon/ http://arstechnica.com/gadgets/2015/07/ibm-unveils-industrys... https://www-03.ibm.com/press/us/en/pressrelease/39250.wss https://www-03.ibm.com/press/us/en/pressrelease/39250.wss
