For my work with Kyle and Vincent in Ottawa, I wanted to showcase more of the interesting configurations of DNA rather than simply passing the DNA through the nanomembrane. DNA Dual End Blockage and Clearage:   DNA Flossing:   DNA…

We manufactured a wafer specifically for SERS experiments in the hope of recapturing larger pore distributions/pore densities that we observed in some of the prototype runs of NPN. Natively, it’s a little thicker, and a little less porous than the…

Kilean and I are working on submitting a paper to Membranes on some of our electron tomography work. Here’s some of the work that we’ve done so far: Tomography Paper V2_KL

We have a wafer that did not clear 500 nm pores (400 nm thick silicon nitride, #4682). There are about 230 chips that could be useful if they were etched a little. I used a SF6 based recipe (15 sccms…

Purpose: We want to know the effects of the RTP process on pore size, pore density for the biased films coming out of the AJA. I believe that the RTP ramp rate is important for forming bigger pores. Some work (Joe…

Presentation: Madejski Proposal Presentation v3 Compressed Document: Madejski Silicon Nanomembrane Microsystem Proposal Final Passed in August 2015. Document was criticized heavily, oral presentation was thought to be good.

With my TEM tilt stack work, we can see a marked difference in the roughness of npMg2 and NPN. Quantifying the bulk roughness properties of the npMgF2 using AFM gives us a way to check that property. Surface roughness has…

We’d like to get verification of the absorption spectra of our npAu/npMgF2 SERS structure. The SERS effect should occur where the absorbance is maximized. Total Light = Absorbance + Reflection||Scattering + Transmittance Last Friday, I had the opportunity to work…

As the title states, these are images from the monolithically fabricated devices used by Kyle and Vincent in Ottawa. These devices were fractured with tweezers, then tilted and metallized with 5 nm of Pt, mounted on carbon tape.    …
