Poly silicon nano ribbons |
Nano ribbons are structures having length and width that is several orders of magnitude larger than their thickness. A typical nano ribbon will have length of 5 to 100 µm, width of 1 to 5 µm but is only 50 to 100 nm in thickness. Silicon nano ribbons exhibit interesting electronic properties and are very promising for biosensing applications. Studying the structure and surface modification of nano ribbons in a transmission electron microscope (TEM) will give us more insight on the working of nano ribbon based devices.
In this project, your task will be to fabricate free standing poly silicon nano ribbons (poly-SiNR) at the Danchip cleanroom at DTU. For the analysis of the fabricated samples, we will begin doing simple current-voltage (IV) measurements and image the poly-SiNRs in the transmission electron microscope (TEM). This will be followed by changing the surface chemistry of the poly-SiNRs and studying its effects by repeating the IV measurements and TEM analysis.
Learning Scope: In this project you will learn about:
1. Micro/nanofabrication technologies.
2. Semiconductor physics
3. Functionalization of nano ribbons
4. Electron microscopy
