Low-cost high-quality crystalline germanium based flexible devices

High performance flexible electronics promise innovative future technology for various interactive applications for the pursuit of low-cost, light-weight, and multi-functional devices. Thus, here we show a complementary metal oxide semiconductor (CMOS) compatible fabrication of flexible metal-oxide-semiconductor capacitors (MOSCAPs) with high-/metal gate stack, using a physical vapor deposition (PVD) cost-effective technique to obtain a high-quality Ge channel. We report outstanding bending radius approximate to 1.25 mm and semi-transparency of 30%. ((c) 2014 WILEY-VCH Verlag GmbH &Co. KGaA, Weinheim)
