Can someone provide me with a relationship between the dissociation constant of the water and the electric field?

At room conditions, and in absence of any electric field, the dissociation constant of water is Keq= 10-14 mol2 L-2. What means that, statistically, [H+] = [OH-] = 10-7 mol L-1. I have found...

COMSOL Multiphysics: How can I manage individual cell values of a mesh in a convergence process?

Using the module Semiconductors for computing electric potential in a certain geometry, sometimes during convergence process one can observe how few cells of the mesh close to both exterior limits...

In the module "semiconductors," how can I manage simultaneously insulating and semiconductor materials?

When I add the option "space charge conservation" included into the module "semiconductor", and assign a specific domain (characterized by a insulating material) to this option, I can compute the...

Does speaking about "semiconductor gases" make sense?

In the context of the band theory of solids, semiconductor character is in general attributed to certain crystalline solids with its Fermi level lying in the gap. In amorphous materials, where the...

Hanbury-Brown Twiss interferometry is generally performed to verify single-photon emission. Are there commercial versions of this interferometer?

Interest in single-photon emitters is growing up for their potential as light sources for quantum cryptography. However single-photon emission is not only difficult to create, but also to detect.

Short Synthesis of Graphene Oxide from Natural Graphite Flakes?

I am in search of a modified Hummer's method, which can be used to synthesis graphene oxide within 6-8 hours. As I am a student it is not allowed for us to work after 5 in the laboratory. So I am...

Abhay A. Sagade

HI,

For resolutions up to 1 um, regular photolithography is good option. but one need to design the mask which is little bit costly. Euro 550 for 7x7 cm2.

For few devices with higher resolution

Angel Luis Alvarez

Oh, Abhay, thank you very much for your detailed response, and sorry for not having answered for so long.
