General Questions and Answers / Zero Band GAp Graphene Schottky diode
« on: March 17, 2011, 05:38 »
Hi all,
I am a new user of this forum and Graphene. I am after a schottky diode with zero band gap or zero turn on voltage. I have come across a model of diode fabricated using a structure similar to FET- Graphene [1].
BAnd gap can be controlled by width of the ribbon as in [2]. A width of around 184 nm would give me around 0.001eV band gap ~ 0 eV. So if I use the same model with ribbon around 200 nm wide and 2 micrometer in L , will i be able to get the required diode. What else should I consider in developing the diode?
Am I thinking in the right direction? Is there any Schottiky diode Graphene manufacturer?
Thanks for your help in advance.
