nano materials
DESCRIPTION
This is my work in progress, as yet bare bones, presentation to high school students, whom I hope to recruit into optical materials research. Feedback would be appreciated.TRANSCRIPT

Faissal and Francis
Who is Faissal?
• Graduate Student, Electrical Engineering• Likes:
– Light (I had cool textbooks)– Materials (I liked the packaging on my potato
chips)
• Research Interests:– Optical Limiting, and Electro-Optic Property
Changes– Solar Cells
Who is Francis?
• Undergraduate Student, Electrical Engineering
What Nanomaterials Can Do?
• Imagine a cell phonethat can project onto walls
• A photochromatic/transition lensthat changes color instantly
• Nightvision goggles thatwork better(http://www.azonano.com)
What You Can Do With Nanomaterials?
• Make smaller, more powerful,lasers, and light emitters
• Make materials that changetheir behavior very quickly
• Make detectors that arevery sensitive
Why Do We Need Nanomaterials?
• Faster, more sensitive, more efficient, higher speeds, lower power consumption, and ability to operate in a greater range of temperatures.
What Are Nanomaterials?
• QW QR QD
How do Nanomaterials Work?
• Electrons are confined in a potential well
What is the Physics and Chemistry?
• Bohr Model
• Pauli
• Band Structure
How Did I Get Interested In Nanomaterials?
• Half-Life
• Alpha Centauri
• Deus Ex
