For exciton-exciton annihilation to occur, two excitons must interact with each other. These interactions are well-characterized for 1D and 2D systems. In a 1D system, we can think of exciton...

In holographic imaging mode, the electron beam encompasses the whole sample, forming a reference wave and an object wave. These waves then interfere with each other to form a hologram, which is...
