European researchers have synthesized silicene - silicon allotrope that forms 2D single-atom sheets. Silicene could rival graphene, can be used to make transistors easily.
Iowa State U researchers discovered graphene behaves like laser when excited by very short light pulses. Graphene's 2 important properties - population inversion of electrons and optical gain. Can be used for optoelectronic devices.
Mich Tech U researchers discovered graphene can make solar cells 52% more efficient than current tech. Graphite oxide powder mixed with titanium dioxide, subsequent paste applied over (glass) and baked to make the cells.
IBM developed graphene/insulator superlattice for IR photonic devices that work at terahertz levels. Can penetrate wood, other solids.
U of Wisc-Milwaukee developed graphene monoxide that's semiconducting. Can more easily scale up graphene-based electronics.
Aixtron (AIXG) BM300 system used by Japan's National Institute of Advanced Industrial Science and Tech to develop graphene-based low-voltage CMOS FET's for power supply <.3V.
