We can use bquote
library(ggplot2)
ggplot(mtcars, aes(hp, mpg)) +
geom_point() +
labs(x = bquote('x axis'~(Å^2)), y = "y axis") +
#or
#labs(x = bquote('x axis'~(ring(A)^2)), y = "y axis")
theme_bw()

Thank you for your answer. How to get the fonts in bold letters? – sara Jun 15 '16 at 04:04

4@sara just add `bold` like `bquote(bold('x axis'~(Å^2))` or `expression(bold(x~axis~ring(A)^2))` – zyurnaidi Jun 15 '16 at 04:27

1@zyurnaiidi Thank you for your comment. square (superscript) doesn't come in bold letter. – sara Jun 15 '16 at 05:54

You should use expression, preferable combined with paste, as follow:
ggplot(mtcars, aes(hp, mpg)) + geom_point() + labs(x = expression(paste("x axis ", ring(A)^2)), y = "y axis")
