Towards clean and crackless transfer of graphene

January 2, 2012
Author(s)
Xuelei X. Liang, Brent A. Sperling, Irene G. Calizo, Guangjun Cheng, Christina Hacker, Qin Zhang, Yaw S. Obeng, Kai Yan, Hailin Peng, Qiliang Li, Xiaoxiao Zhu, Hui Yuan, Angela R. Hight Walker, Zhongfan Liu, Lianmao Peng, Curt A. Richter
We present the results of a thorough study of wet chemical methods for transferring chemical vapor deposition grown graphene from the metal growth substrate to a device compatible substrate. Based on these results, we have developed a "modified RCA clean"

Flexible Memristors Fabricated through Sol-Gel Hydrolysis

May 1, 2011
Author(s)
Joseph L. Tedesco, Nadine Gergel-Hackett, Laurie Stephey, Andrew A. Herzing, Madelaine H. Hernandez, Joseph J. Kopanski, Christina A. Hacker, Curt A. Richter
Memristors were fabricated on flexible polyethylene terephthalate substrates consisting of an oxide film generated through hydrolysis of a spun-on sol-gel. X-ray photoelectron spectroscopy, spectroscopic ellipsometry, transmission electron microscopy, and

Conduction and Loss Mechanisms in Flexible Oxide-Based Memristors

March 21, 2011
Author(s)
Joseph L. Tedesco, Nadine Gergel-Hackett, Laurie Stephey, Andrew A. Herzing, Madelaine H. Hernandez, Christina A. Hacker, Jan Obrzut, Lee J. Richter, Curt A. Richter
In order to study the conduction and loss mechanisms behind their operation, flexible sol-gel based memristors were fabricated with differing oxide film thicknesses and device sizes. XPS, TEM, EELS, and VASE measurements indicated the oxide was amorphous

Metal-Molecule-Silicon Junctions Produced by Flip Chip Lamination of Dithiols

February 1, 2011
Author(s)
Michael A. Walsh, Curt A. Richter, Christina A. Hacker
The integration of organic molecules with silicon is increasingly being studied for potential uses in hybrid electronic devices. Creating dense and highly ordered organic monolayers on silicon with reliable metal contacts still remains a challenge. A novel
