Hi Kapil,

The simplest way to make rectifier is to make Diode first. There are several ways you can achieve that..

Once you successfully made diode using any of the above methods, you can easily make high frequency rectifier using that diode. You can check my above paper to know how.

Hope this will provide you some direction.

Good luck.

Hi Kapil,

For graphene you just need to open the band-gap. That's it.. There are many ways to do that, either electrostatic or chemical doping or even using bi-layered Gr or Nano-ribbons. The paper only demonstrate a similar strategy. Regarding CNTs, you can find all the differences with Graphene in electronic devices, optoelectronic devices, chemical doping etc in this article below. Tried to help you and provided some information, signing-off from here. Hope this will help you further.

Good luck.
