Structures Properties P. S. Weiss, The
Pennsylvania State University
Technology Issues Gain molecular level control
of films and 3D structures to tailor properties
and functions of molecular-scale components and
devices for use in critical future Navy and
commercial technologies.
Objectives Develop means to measure, to
quantify, to predict, and to control
nanometer-scale properties.

• Approach
• control placement of molecules and particles in
  films and 3D structures
• use and develop new scanning probe microscopy
  to address single and bundled molecules and
  nanostructures
• vary molecular and assembly structures, to
  measure and optimize electronic and other key
  properties

• Impact Transitions
• joined DARPA Moletronics Program
• technology being developed and used
  collaboratively with Atolytics, Air Products,
  BP/Amoco, Charles Evans, Exxon/Mobil, IBM, and
  PPG
• brought area to Joint Vision 2010 Workshop on
  Advanced Technologies and Experiments for Future
  Joint Warfighting

• Accomplishments
• developed new means to measure single molecules,
  particles, and assemblies across a broad
  frequency range
• developed new means to manipulate
  molecular-scale film properties via control of
  defects
• developed means to control local polarization in
  ferroelectric films
