How to build a nanostructure with different surfaces??

Hi everyone!!

How can I build a nanosructure which shows different type of surfaces???

in the details I'm talking about Gold Nanorod, a rod-shaped particle with an axes longer than the other and it is composed of different Au surfaces (such as 111, 110, 100...)

How can I combine different Au surfaces in a single system??

every kind of observation/suggetsion will be really appreciated

thanks in advance
