The chemical composition of nonstoichiometric compounds do not respect the law of definite proportions.
P. Kofstad has written: 'Nonstoichiometry, diffusion, and electrical conductivity in binary metal oxides'
ZnO has an n-type character because of presence of nonstoichiometry that is absence of elemental composition that can be represented by a ratio of well-defined natural numbers.This n-type behaviour is due to point defects like vacancies and interstitials in the ionic crystal. An alternate reason presented , based on theoretical calculations is the unintentional substitutional hydrogen impurities in the compound.
It mean what you don't what does it mean.
Mean is the average.
What does GRI mean? What does GRI mean?

The correct usage is "what DOES it mean"
he was a mean person who lived with mean people in a mean castle on a mean hill in a mean country in a mean continent in a mean world in a mean solar system in a mean galaxy in a mean universe in a mean dimension
No, but sometimes "average" means "mean" - when it doesn't mean median, geometric mean, or something else entirely.
He is as mean as a copperhead snakeHe is as mean as an angry bearHe is as mean as a bottle of brandyHe is as mean a black woman
Present - I mean, She means. Future - I will mean, She will mean. Past - Meant.
