Surface Grafting of Polypyrrole onto Silicon Wafers

August 1, 2007
Author(s)
Daeson Sohn, Hyoseung Moon, Michael J. Fasolka, Naomi Eidelman, Sang-Mo Koo, Curt A. Richter, Eun S. Park, Joseph Kopanski, Eric J. Amis
A micromolding technique in capillaries was adapted to make uniform patterns of polypyrrole (Ppy), and the conductivities of the patterns were measured by direct contact IV curves and conductance AFM methods. Noncovalently bound Ppy patterns have high

Random Telegraph Signals in n-type ZnO Nanowire Field Effect Transistors at Low Temperature

July 30, 2007

Hao Xiong, Wenyong Wang, Qiliang Li, Curt A. Richter, John S. Suehle, Woong-Ki Hong, Takhee Lee, U Falke
Single-crystal ZnO nanowires have been fabricated as field effect transistors (FETs). The characteristics of low frequency noise in the drain current of n-type ZnO FETs have been investigated through random telegraph signals (RTSs) at 4.2 K. At room

Silicon Nanowire Electromechanical Switches for Logic Device Application

July 6, 2007
Author(s)
Qiliang Li, Sang-Mo Koo, Monica D. Edelstein, John S. Suehle, Curt A. Richter
Electromechanical switches consisting of chemical-vapor-deposition grown silicon nanowires suspended over metal electrodes have been fabricated successfully by using single nanowires manipulation and compatible photolithographic processes. The switches are

Effects of Ozonolysis and Subsequent Growth of Quantum Dots on the Electrical Properties of Freestanding Single-walled Carbon Nanotube Films

L C. Teague, S Banerjee, S S. Wong, Curt A. Richter, Bindhu Varughese, J Batteas
A significant challenge exists in probing the transport behavior of chemically modified single- walled carbon nanotubes (SWNTs). Thin films of SWNTs offer one facile approach to integration of these materials into electronics and sensing applications. Data

Silicon Nanowire on Oxide/Nitride/Oxide for Memory Application

May 16, 2007
Author(s)
Qiliang Li, Xiaoxiao Zhu, Hao Xiong, Sang-Mo Koo, D. E. Ioannou, Joseph Kopanski, John S. Suehle, Curt A. Richter
We report the fabrication and characterization of Si nanowire memory devices with oxide/nitride/oxide stacked layers as the gate dielectrics and charge storage media. The devices were fabricated by using photolithography to pattern the metal contacts to

On-Chip Characterization of Molecular Electronic Devices using CMOS: The Design and Simulation of a Hybrid Circuit Based on Experimental Molecular Electronic Device Results

March 11, 2007
Author(s)
Nadine Gergel-Hackett, Garrett S. Rose, Pater Paliwoda, Christina Hacker, Curt A. Richter
The focus of the field of molecular electronics in recent years has been mostly limited to the development of molecular electronic test devices and the characterization of electron transport through organic molecules. However, in order for molecular

Precise Manipulation and Alignment of Single Nanowire

March 2, 2007
