Author(s)

Ronaldo Minniti, John D. Gillaspy, L P. Ratliff

Nanoscale dots created on the surface of a HOPG sample by bombardment with individual highly charged xenon projectile ions were observed using an in-situ scanning tunneling microscope (STM). This is the first time that such features have been created and

Separation of Inner Shell Vacancy Transfer Mechanisms in Collisions of Slow Ar 17+ Ions with SiO 2

January 1, 2001

E Takacs, Z Ber nyi, John D. Gillaspy, L P. Ratliff, Ronaldo Minniti, J Pedulla, R Deslattes, N Stolterfoht

We have studied the spectrum of x-rays emitted when hydrogen-like argon ions impact silicon dioxide surfaces. Specifically, we were interested in the mechanism for creation of K-shell holes in the silicon target atoms, which can be filled with the release

Exposure of Self-Assembled Monolayers to Highly Charged Ions and Metastable Ions

July 1, 1999

Author(s)

L P. Ratliff, Ronaldo Minniti, A Bard, E W. Bell, John D. Gillaspy, D Parks, A J. Black, G M. Whitesides

The doses of neutral metastable argon atoms (Ar*) and highly charged xenon ions (HCIs) required to damage self-assembled monolayers (SAMs) of alkanethiolates on gold are compared in a set of experiments carried out concurrently. The extent of damage to the
