66 days left: crystal growth

Still counting! 66 days left 😀 Yesterday Henrik and I worked quite a bit on the special topics 5 credits course I need to take before I finish the PhD. We are working on faceting of silicon carbide nanocrystals, so we decided that learning about crystal growth is only natural to learn the terminology in the field and also relevant theory.

We are using this book by Alberto Pimpinelli and Jacques Villain:

 

 

 

 

 

 

 

 

which turns out to be a very weird book. Some things are explained in great detail, but some of the harder stuff have both typos (missing important factors) and a lack of explanation. I’m both impressed and disappointed at the same time.

So what is crystal growth? It is when you have a crystal (atoms sitting in a crystal lattice) and atoms are still changing the shape of the crystal. Maybe the crystal is surrounded by gas so every now and then another atom joins the crystal, diffuses around until it settles down in a nice place.

I also realize that these blog posts will sometimes explain good and often not 😛 My current thoughts are what I’ll write down and that might be messy sometimes =)
