I wish there was a place I could go to read translated versions of notes kept by German scientists. They did horrible things but some of the other research was really cool like what I've learned about their attempts in creating nuclear power.
Not quite the same, but immediately after the war a number of prominent German scientists were interned at Farm Hall, in England, and secretly recorded for months. The full transcripts are available (https://books.google.com/books?id=pzNjntMMq-oC) and it's interesting to hear what Heisenberg and Otto Hahn thought of the Nazis and the successful American nuclear bomb. The transcripts were also adapted into a pretty good stage play a few years back.
Would that play be Copenhagen (https://en.wikipedia.org/wiki/Copenhagen_(play))? If so, I highly recommend the BBC adaptation with Daniel Craig as Heisenberg, Stephen Rea as Niels Bohr, and Francesca Annis as Margrethe Bohr.
The Nazis had a very strange relationship with science; ideas were rejected because the person to propose them was Jewish. Since many of the top scientists at that time were, in fact, Jewish, they rejected the new development with regards to quantum mechanics and basically most now established new theory in favor of going after 'German physics'.
"German scientists" is rather a broad category, covering people from Joseph Mengele to Werhner von Braun. The latter has a large number of works in English.
