Replacing cathodoluminesc. by gates

[physengineer]

Hi,
I appreciate any help in this regard:

People have used cathodoluminescence to study defects in insulators by having energetic electron beam on the defect and observing the luminescence.

I want to see if I can do the same thing instead by putting gates around that defect. I can also dope my insulator to make it into semiconductor if it helps.

I have no idea where to begin or how to model it. If you are aware of any similar situations in any system or even a simple clue I would appreciate it if you could share it with me.

Thanks a lot in advance!

There are several approaches you can take depending on what you are trying to achieve. If you are looking to study the defect in more detail, you could use Scanning Tunneling Microscopy (STM). This allows you to study the electronic structure of the system at a very small scale. You can also use capacitance-voltage measurements or conductance-voltage measurements to study the properties of the defect. You can also use optical techniques such as Raman spectroscopy or photoluminescence to study the electronic structure. Finally, you can also use the electric field from the gates to control the charge state of the defect, allowing you to study its behavior.
