SUMMARY

The discussion focuses on calculating the probability of two substitutional dopants residing in adjacent lattice sites within a crystal structure. Given a dopant concentration of 5% and a coordination number of 8, the probability of a single dopant being isolated is calculated as (1-0.05)^8. This formula serves as a basis for further calculations regarding the likelihood of adjacent dopant placement in solid-state physics.

PREREQUISITES

Hi,

Could someone explain how to calculate the probability that two substitutional dopants will reside in adjacent lattice sites.

For example, given a dopant concentration of 5% and a crystal structure in which each lattice site/atom is coordinated to 8 others what is the probability of finding two dopant atoms residing in adjacent lattice sites?

Thanks for any insight!

Well, the probability of a dopant being isolated would be (1-0.05)^8 (using your example). I'm sure you can figure out the rest.

Claude.
