We report the dielectric and ac conductivity studies on the organic molecular ferroelectric, diisopropylammonium bromide polycrystalline sample. The frequency and temperature dependant real and imaginary parts of the impedance show two relaxations in the sample. The Nyquist plots exhibit two semicircles revealing both grain and grain boundary contributions to the resistance above Curie temperature...
In this paper we demonstrate the design and development of a small-size, sheet-fed gravure printer which can achieve 10 mum alignment of multiple layers and requires less than 200 muL of ink per print. Using this printer we demonstrate highly-scaled metallic silver lines, 20 mum wide, printed with nano-particle and precursor based inks. We describe some scaling trends which are specific to the printing...
New process modules and device architectures for (sub-) 32 nm CMOS lead to both opportunities and challenges for analog/RF and mm-wave circuit design. A survey will be given describing the advanced process modules and competing architectures (planar bulk CMOS versus FinFETS), and their impact on analog/RF performance. FinFETs will be shown to be better suited for analog baseband design and to have...
Printing is considered an attractive technology for realizing electronic functionality at low cost. Inkjet printing, in particular is very attractive for applications requiring low material consumption and spatially-specific material deposition. We report on inkjet-printed transistors offering performance approaching that of amorphous silicon, fabricated using nanoparticle-based metallization and...
