An Afternoon

One afternoon I had some time to play with the microscope during my school days. The moment I was out of sight of my teacher, I started looking at the things that I use every day. I still remember very vividly looking at a dead mosquito. Of course, I ate mosquitos every day ;).

Life have changed and now every afternoon I get to play with the microscope. Below you see a picture of my smartphone screen. On the top row is the picture as we see and in the bottom row is what I saw under the microscope. The matrix of red, blue, and green OLED (Organic Light Emitting Diode) lights up in different combinations and intensities to produce the 16 million colors that we see. We use it every day and technology has been around for a while now. But still to see it in action is very exciting.

These are some of the different types of devices I am working on now. They don´t look as beautiful as a mosquito. On the left we see a device with platinum contacts made with e-beam lithography with a 2D ferromagnet flake encapsulated with boron nitrite. On the right is another device with gold contacts in transverse and longitudinal geometries.
