# Catalyst Diffusion

The inven­tion: Nanos­truc­ture device and method for man­u­fac­tur­ing nanos­truc­tures – A method for man­u­fac­tur­ing a plu­ral­i­ty of nanos­truc­tures on a sub­strate. The method com­pris­es the steps of: deposit­ing a bot­tom lay­er on an upper sur­face of the sub­strate, the bot­tom lay­er com­pris­ing grains hav­ing a first aver­age grain size; deposit­ing a cat­a­lyst lay­er on an upper sur­face of the bot­tom lay­er, the cat­a­lyst lay­er com­pris­ing grains hav­ing a sec­ond aver­age grain size dif­fer­ent from the first aver­age grain size, there­by form­ing a stack of lay­ers com­pris­ing the bot­tom lay­er and the cat­a­lyst lay­er; heat­ing the stack of lay­ers to a tem­per­a­ture where nanos­truc­tures can form; and pro­vid­ing a gas com­pris­ing a reac­tant such that the reac­tant comes into con­tact with the cat­a­lyst layer.
