New laptop for the TECAN and DLS is finally hooked up
Over the past few days Josh and I installed windows 7, windows office suite, Malvern’s Zetasizer software (available online), Tecan’s I-control software (available in the 3-ring binder in the glass cabinet above the machines), and chrome onto the new(er) laptop in the basement. I copied the files on the old computer that seemed relevant –…
BBB Device V2.6
Given the results of my previous post, I am reworking my design to make it more manufacturable. BBB Device V2-6 Compressed The major change compared to my last design is the inclusion of a full length microscope slide and coverslip. Instead of cleaving the electrodes from the glass, this step eliminates the need to…
Updated: 25-40-25 nm OSO SEPCONS
We created a 25-40-25 OSO stack with a SEPCON pattern. RTP at 1050 C 100 C/s 60 s. The following images show a comparison between the STEM detector and the SEM detector, and then a couple more images at 100 kx and 50 kx. I calculated a porosity of ~6.5 %, and…
Morphology evolution in pnc-Si membrane(2)
ByJoe QiIn the last post, we have discussed the intermediate state of the membranes which shows the irregular shape pores and silicon nanocrystals after annealed at 700C. Last week I did a quick test on the same nitride membrane with a different annealing process to verify this intermediate state. I run two different heat treatments. The…
