Grading

• 70% Oral Exam

• 20% Presentation

• 10% Class Participation

Project Assignment: Special topic student presentation and report.

 

Datum x: Presentations (Topics 1-5): One or at most 2 students reviews a selected area and proposes a new research activity in a 20 minute talk and two page report that will be graded

  Datum y:  

Presentations (Topics 6-8): One or at most 2 students reviews a selected area and proposes a new research activity in a 20 minute talk and two page report that will be graded

You will prepare a special topic student presentation and report describing a new/original idea that you develop.

Details: Depending on the class size, students work as individuals or in a small group (group size <= 2).

At the beginning of the semester you sign up for a topic of your choice. You review the selected area and propose a research activity in a 15 minute long talk + 5 minutes questions.

Together with your oral presentation you hand in a 1-2 page long report to pitch the idea. Originality, ability to present the idea, and ability to provide scientific sound answers to questions are learning goals.

The topics are as follows: (2) NanoScale Imaging, (3) Conventional Nanoscale Lithography/Patterning, (4) Unconventional Nanoscale Lithography/Patterning, (5) Nanomaterials: Properties, Synthesis, and Applications , (5) Nanoelectronics using Nanomaterials , (6) Nanosystems manufacturing: Heterogeneous Integration and Self-Assembly, (7) own topic in the field of Nanotechnology.

Homework 1: (Due in next class) Name:

1.Read the lecture on nanotechnology by R.P. Feynmann, "There's Plenty of Room at the Bottom": http://www.zyvex.com/nanotech/feynman.html

Provide Answers:

How important is inertia in the nanocar?

What is the difference between metal, plastics, and glass?

What is a problem as you go down in size in terms of force?

Will the bold fall down?

Has the price been won?

The vision

The classic talk: “There's Plenty of Room at the Bottom ”Richard Feynman, December 29, 1959. The annual meeting of the American Physical Society at Caltech

•“Why cannot we write the entire 24 volumes of the Encyclopedia Britannica on the head of a pin?”

•“Biology is not simply writing information; it is doing something about it. A biological system can be exceedingly small.”

•“I want to build a billion tiny factories, models of each other, which are manufacturing simultaneously, drilling holes, stamping parts, and so on.”

The vision (A)

Nanostructures:

a. Contain a countable number of atoms

b. Suites for atomic level detailed engineering

c. Provide access to realms of quantum behavior that is not observed in larger (even 0.1 µm) structures

d. Combine small size, complex organizational patterns, potential for very high packing densities and strong lateral interactions, and high ratios of surface area to volume.

The vision (B)

Small => …means not only x1000 smaller but also….a. High packing density

b. Potential to bring higher speed to information processing

c. Higher area and volumetric capacity to information storage.

d. Dense packing is also the cause of complex electronic and magnetic interactions between adjacent (and sometimes nonadjacent) structures.

e. The small energetic differences between the various possible nanostructures configurations may be significantly shaped by those interactions.

Vision….(C)

New established disciplines:

Electronics: nanostructures represent the limiting extension of Moore’s law and classical devices to small devices, and they represent the step into quantum devices and fundamentally new processor architectures.

Molecular biology: nanostructures are the fundamental machines that drive the cell —histones and proteosomes—and they are components of the mitochondrion, the chloroplast, the ribosome, and the replication and transcription complexes. In catalysis, nanostructures are the templates and pores of zeolites and other vitally important structures.

Materials science: the nanometer length scale is the largest one over which a crystal can be made essentially perfect. The ability to precisely control the arrangements of impurities and defects with respect to each other, and the ability to integrate perfect inorganic and organic nanostructures, holds forth the promise of a completely new generation of advanced composites.

Please Note: Some of the text should be categorized as Science fiction since it violates some fundamental physical laws. It still is very interesting.
