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.

“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.
