Energy Harvesting

Last week, we created a series of wafers that were RTPed at four different temperatures between 900 C and 1000 C.  Below is a comparison of the 900 C (left) vs. 1000 C RTP (right) wafer. We see that a difference of 100 C shifts the cutoff ~10 nm.  The pores are also the roundest…

Yesterday I posted results of a diffusion experiment using rhodamine and fluoroscein that showed the pores in SC269 are open both before and after treatment in the UV-Ozone system. I set up another diffusion experiment to test “treated” and “untreated” SC269 samples with diffusion of BSA and DDM. As a reminder the focus of my…

I briefly experimented with the track-etched membranes this morning and found that they are extremely fragile and near impossible to cut. I disassembled a few of the microcons and found that a circular piece of paper the size of a hole punch (like the one on the bench by the mac) fits perfectly into the…

The following data is from analysis of Wafer #1059, consisting of 30nm pnc-Si with 7% porosity and an average pore diameter of 28nm. Square window sizes with sides lengths of 0.1mm, 0.3mm, 0.5mm, 0.7mm, and 0.9mm were tested. For 1.1mm x 1.1mm windows, burst pressures could not be determined, as these windows did not etch…

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.
