-2 Power law for density vs. pore size

Following up on our previous work with SiN-NP with varied RIE times, Sarah and I measured permeability and permeance using a new measuring system better suited to the higher permeance and permeability we expect with the larger pores and higher porosity. Using the pressure regulator pictured above, we can set pressures of 3 psi and above…

As a proof-of-principle, Henry and I have been working on a microfluidic device for flowing blood cells/particles across cultured cells on pnc-Si.  More on why this is important later.  We’ve come up with a prototype and I’ve been testing it out.  I will include schematics later but here are the first couple of movies I’ve…

Summary I want to imitate the material properties from 1085 as they have given us the best SERS performance to date. We have the best information that we’ve ever had before imitating the nanostructure and nanotopology from the MgF2. Our belief is that getting infilled Au close together in a nanopore dramatically enhances the electric…

We have already established that bias is an important parameter in controlling the morphology of 15 nm thick pnc-Si, but have yet to look at its effect on thicker films. This week, made a few 30 nm thick Si films with 02, 05, 25, and 50 W of substrate bias. I annealed these films at…

Inspired by JP, we decided to try to etch amorphous (unannealed) wafers this week to see if pinhole density changed.  To my surprise, the amorphous membranes had no pinholes!  Furthermore, I tried to anneal the membranes after the etch and they went flat indicating crystallization!  Refer to the table below for the results. Wafer 565:…
