Raman imaging analysis of sic wafers
Webb24 juli 2024 · Non-classical crystallization suggests that crystals can grow with nanoparticles as a building block. In this case, the crystallization behavior depends on the size and charge of the nanoparticles. If charged nanoparticles (CNPs) are small enough, they become liquid-like and tend to undergo epitaxial recrystallization. Here, the size … Webb1 sep. 2003 · Raman mapping is an imaging scan technique that employs point-topoint scanning to measure adjacent sample micro-regions sequentially. The carrier …
