GaFIB modification of gallium based material

Have you ever wondered what happens when a gallium-based material is modified with a focused beam of ions of the same element?
In the photo you can see the effect of just such an event.
Gallium grains precipitated under the modified GaAs surface and they are not small at all. Sometimes this may be expected, but it usually crosses our scientific plans. If we want to avoid this, we should modify the samples with a beam of another element, like xenon plasma.
Such a solution in Poland is only possible in our laboratory and we are proud of it and constantly improve our skills.
We invite you to cooperation!
