Tradition maintained - two papers for oral in IEEE NANO 2013


1)      Abdulilah Mayet, Casey Smith, Muhammad Hussain, “Energy Reversible Switching from Amorphous Metal based Nanoelectromechanical Switch”, IEEE NANO 2013, Beijing, China, August 5-8, 2013


We report observation of energy reversible switching from amorphous metal based nanoelectromechanical (NEM) switch. For ultra-low power electronics, NEM switches can be used as a complementary switching element in many nanoelectronic system applications. Its inherent zero power consumption because of mechanical detachment is an attractive feature. However, its operating voltage needs to be in the realm of 1 volt or lower. Appropriate design and lower Young’s modulus can contribute achieving lower operating voltage. Therefore, we have developed amorphous metal with low Young’s modulus and in this paper reporting the energy reversible switching from a laterally actuated double electrode NEM switch.


2)      Ramy Qaisi, Casey Smith, Mohamed Ghoneim, Muhammad Hussain, “Direct Measurement of Graphene Contact Resistivity to Pre-deposited Metal in Buried Contact Test Structure”, IEEE NANO 2013, Beijing, China, August 5-8, 2013
We demonstrate a buried contact based novel test structure for direct contact resistivity measurement of graphene-metal interfaces. We also observe excellent contact resistivity ~1 µΩ-cm2 without any additional surface modification suggesting that the intrinsic Au-graphene contact is sufficient for achieving devices with low contact resistance. The chemical mechanical polishing less test structure and data described herein highlights an ideal methodology for systematic screening and engineering of graphene-metal contact resistivity to enable low power high speed carbon electronics.
