Advisor: Dr. G.-C. WangAdvisor: Dr. DJ Wagner Fran Mateycik Rensselaer Polytechnic Institute ScIT is unique because: It is an upper-level physics course with no prerequisites; It combines discussions of fundamental physical principles with information system applications that interest students; It brings world-class researchers with several different specialties into a classroom to talk about the current state of research; It attracts students from diverse concentrations, with performance in the course essentially independent of physics background. Posterboard Analogy (Energy Bands) N-TypeP-Type Nanocar Graphite Interconnect Goal: Create Demonstrations that may be helpful for the ScIT courses and Physics Outreach. Physics Education Research Conference The course material has a very broad range of physics topics including these four units: Information Transfer, Information Storage, Information Processing, and Future Information Technologies. I worked with Dr. Wagner more specifically to add material to computing implications of nanotechnology section. My projects included animating and illustrating the mechanical properties of nanotubes and interconnects, while verifying sources and facts within the text created a year previous. I also helped develop animations based on our current computing technology. Energy bands, electron and hole movement, semiconductors, and doping are all as important as nanotechnology for our future technology. They are also basic physics concepts that could apply to possible future uses of nano-structures. These few pictures illustrate some examples of work done. The Science of Information Technology course material is being heavily revised and the NSF has funded a project to develop a complete online textbook. With this new textbook, along with this very unique course, educators envision a growth in educated technology users in our coming generations. My primary responsibility for the first five weeks of REU were to create material for the nanotechnology portion of the online text. Goal: Create Nanotechnology demonstrations that may be helpful for the Science of Information Technology Course. Goal: Create Nanosprings demonstrations that can be used for Physics Outreach. The annual meeting for PERC was held in Madison Wisconsin. Dr. Wagner, along with JJ Rivera and I went to the Conference for the presentation of our findings related to the cognitive model of optical fibers and Total Internal Reflection. The assessment of student preconceptions and mental models in physics seems to be a great way to understand and better fulfill a student’s educational needs. With the help of Dr. Sybillyn Jennings (Psychologist at Russell Sage College) and undergraduate assistants (including me ), Dr. Wagner has produced several outlines based on the progression of cognition within the students’ mind for optical fibers and Total internal reflection. These outlines are very helpful for future creation of curricular materials because they allow us to change preconceptions and allow related physics subjects to connect more easily in the students’ mind. Science of Information Technology (ScIT) is a novel course introducing students to the physics underlying information technologies. Since the tip of the cantilever of the AFM is covered in Pt, one can easily pass current into the tip and into the Co covered springs. Since current passes through the spring like a wire, a magnetic field in the coil is generated. The current flowing in the coils are in the same direction and therefore an attractive force between neighboring turns of the spring will be created. The attractive forces compress the spring and the tip of the cantilever breaks contact with the top of the spring, therefore breaking the circuit. Since the magnetic force is induced by the flow of current, the magnetic force will disappear with the break in the circuit and the spring will return to its original state. Once it returns to such a length, the tip will touch to top of the spring once again and reconnect the circuit, starting another cycle of compression and restoration. These demonstrations were created to expand the general understanding of one particular section of the vast nanotechnology field. These animations target high school and accelerated middle school students and are designed to both stand on their own or be used as guides for classroom instruction. Since I am a coordinator for many Physics Outreach Events, these animations, along with the knowledge of how to create more Macromedia Director animations, will be very helpful in the next couple years as physics outreach for the department grows. Also, since they are published online, others will be able to access these files and learn more about Nanosprings. To the side, we can see five screen shots of the Nanosprings animation. The first screen shot is of the menu where we can see a listing of the topics covered (the numbers following the topics listed below represent the screen shot number.): Hooke’s Law [2], Oblique angle Deposition using Electron beam evaporation [3], Glancing Angle Deposition using Thermal evaporation [4], and nanospring mechanics [5] which just happens to be very similar to that of Macroscopic Springs I am very close to finishing the instructional movies based on Nanosprings. The section that must be finalized is based on current research done here at RPI. Dr. Singh along with several other graduate students in Dr. Wang’s group are studying the compression of Cobalt covered nanosprings due to an attractive magnetic force between the coils after passing a DC current through a Platinum coated conducting AFM tip. Macromedia Director Program The concept is based on simple electromagnetic and mechanical properties that may be useful in the future.
