BBB Device V2-8 with vias through bulk silicon

I ran another diffusion cell last week using Human Albumin and Cytochrome C. I increased the volume of PBS because the last time I ran the gel for this mixture, the band for cytochrome c was very prominent. Out of the three chambers of the diffusion cell that I ran, only one of them actually…

After some experimentation with acetylene concentration and anneal temperature, I was able to find a carbonization recipe that appears to shrink our pores by 1/3 the original diameter.  Below are images of an untreated sample (TEM 148: 15 nm pnc-Si 1000 RTP) and a carbonized sample (see recipe at end of post). A closer look…

I’ve been working with the AFM recently and have had some success getting images on supported pnc-Si films. Yesterday, I imaged three samples from sc 698: one untreated pnc-Si film and two films coated with aluminum oxide (1.5 nm and 5 nm thickness). Here are the scans (500 nm x 500 nm). The topmost scan…

Hello Everyone, For the next figure in our paper, and to make the transition happens smoothly from Track Etched membranes to NPN membranes, we decided to run the same beads experiment on NPN membranes as well. So Kilean and i started working on these experiments, and the first experiment was to capture and release 100…

Using the same successful procedure as the last lift-off attempt, another large piece of membrane lifted off. This came from the same wafer, but confirms that 30 minutes in BOE is sufficient to etch 25 nm of thermal oxide under the SU8 structure. Ideally this time can be reduced by means of a different sacrificial…
