STM vibrational compensation

I’ve a long standing interest in STM projects since seeing the various low cost and amateur project attempts many years ago. I recently came across this paper describing a method for compensating for the probe vibration. The results (shown on HOGP below) see quite impressive. And allow for a scan rate of a few hundred …

A 2N2222 die image

I was curious to know what a transistor die looked like so I hacked the can off a 2N2222 and up it under my recently acquired microscope. The die image is above, I’m not sure if I cracked it opening the can or blew it up (it was suspect anyway). Interesting to note that it …
