Outline

• Objective
• Motivation
• Project Time Table
• Application of Research Project

3
Objective

• To study the electrical and mechanical
  properties of carbon nanotubes in order to
  determine the band structures
• Semi-conductor
• Metallic
• Nano scale device manufacturing
• Sensors
• Actuators
• Others

4
Motivation

• Carbon nanotubes (CNTs) have been intensely
  studied, and are good candidates for many
  electronics and sensing applications.
• The increase need for making electronics smaller,
  and their excellent electrical and mechanical
  properties
• These potentials cannot be achieved unless CNTs
  with semiconducting and metallic band structure
  can be successfully deposited and separated

DEP Stuff
Dielectrophoresis (DEP) is the motion of a
particle caused by polarization effects of a
non-uniform electric field.
DEP force equation where v is the volume of the
particle, e m is the mediums dielectric
constant.
ar is the Clausius- Mosotti factor that relates
the dielectric constants of both the medium and
the particle. Can vary between -0.5 and 1. If
positive then DEP, if negative then DEP.
