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.
