What’s the procedure in Top-down fabrication method? |
A. | nano-particles -> powder -> bulk |
B. | powder -> bulk – > nano-particles |
C. | bulk -> powder – > nano-particles |
D. | nano-particle – > bulk -> powder |
Answer» C. bulk -> powder – > nano-particles | |
Explanation: top-down approach is the one in which a material of regular size is converted into a nano-particle. in the bottom-up approach, the atoms are joined to form nano-particles. |
