Helium Ion collision with diamond wafer

In summary, the conversation discusses the potential outcomes of a Helium ion colliding with a diamond wafer surface. It is debated whether the ion will lose its charge by gaining an electron from the insulating surface or if it will have an elastic collision with no net energy loss or gain. The difficulty level of the topic is changed from graduate to undergraduate, and the opinions of various physicists with different levels of education are shared on the matter. It is also questioned whether an undergraduate would be able to answer the question.

If a Helium ion He+ collides with a diamond wafer surface, an insulator, does the Helium ion, at 25 deg C,
will the ion lose it's charge by gaining an electron from the insulative surface or does the ion have an elastic collision with no net energy loss or gain?

Freshly cleaved diamond?
 
  • #3
The diamond wafer surface is chemical vapour deposited CVD onto a conducting surface probably copper.

... and, "Up jumps the devil."
 
  • #5
Thread difficulty level changed from "A" (graduate school) to "I" (undergraduate).

I appreciate that you have chosen to change thread difficulty.
Separate to the physics forum on this particular question the answers per level of education have been as follows:

1/ Particle Physicist, MSC, collisions elastic.
2/ Physicist, mathematician, BSc, collisions elastic.
3/ Physicist,Ukrainian Professor, collisions elastic.
4/ Nuclear Physicist, PhD, German elastic.
5/ Australian Professor, ANSTO, initial consideration elastic, then changed to inelastic.

Accordingly, I wonder whether an undergraduate would be able to answer the question.

There is a third option that both processes are possible.
 

1. What is the purpose of studying Helium Ion collision with diamond wafer?

The purpose of studying Helium Ion collision with diamond wafer is to understand the interactions between these two materials and how they affect each other's properties. This can help in developing new technologies and applications in fields such as nanotechnology, materials science, and electronics.

2. How does Helium Ion collision with diamond wafer affect the surface of the wafer?

Helium Ion collision with diamond wafer can cause defects and damage on the surface of the wafer due to the transfer of energy and momentum between the particles. This can alter the surface morphology, crystal structure, and electronic properties of the wafer, affecting its overall performance.

3. What are the potential applications of Helium Ion collision with diamond wafer?

Some potential applications of Helium Ion collision with diamond wafer include creating nanoscale patterns on the surface of the wafer, modifying its surface properties for better adhesion and friction, and improving its electrical conductivity and heat resistance for use in electronic devices and sensors.

4. How does the energy of the Helium Ion affect the collision with diamond wafer?

The energy of the Helium Ion is a crucial factor in the collision with diamond wafer as it determines the amount of energy and momentum transferred to the wafer. Higher energy collisions can result in more significant damage and modifications on the wafer surface, while lower energy collisions may have little to no effect.

5. What techniques are used to study Helium Ion collision with diamond wafer?

There are various techniques used to study Helium Ion collision with diamond wafer, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, and atomic force microscopy (AFM). These techniques allow for the visualization and analysis of the surface modifications and interactions between the Helium Ion and the diamond wafer at the nanoscale level.
