For the past few months since I started my work here in Gothenburg, the weather has been rainy at least half of the time! Even for me who loves the rain, it can get annoying sometimes. On the other hand, long winter nights would severely affect the energy level of someone without a routine to stick to (and of course, vitamin D pills!). Thankfully, it was easier for me as I am busy with the measurements and cleanroom training almost all the time, and I can’t really feel how fast the days pass by.
Although I still have to get the licenses for the cleanroom tools, I am being trained and partially doing fabrication with the help of one of our postdocs who is also mentoring me. Coming from a simulation background, it truly fascinates me how I can fabricate real-life devices and measure them. Last week we finished my first simple spin Hall nano oscillator chip and since then, I’ve been doing auto-oscillation measurements on it to determine the signal (and the device) quality. If everything goes well, we will fabricate Memristive gates on top of them, which is a very complex procedure. Afterward, we will investigate the effects of those Memristive gate’s position and shape on spin Hall nano oscillator chains and arrays.
