What was discovered

They described the growth mode of a crystalline film on a substrate in which one or more complete layers first form, followed by three-dimensional islands. It is the basic mechanism behind semiconductor quantum dots.

The paper is from 1938 (Sitzungsberichte der Akademie der Wissenschaften in Wien); the work was done in Sofia, where Stranski was a professor. With Kossel Stranski also formulated crystal-growth theory.

What it led to

  • self-assembled quantum dots
  • epitaxy of thin films and semiconductors
