AUCTeX provides a variable called `LaTeX-electric-left-right-brace' for
this purpose which is initally disabled:

,----[ C-h v LaTeX-electric-left-right-brace RET ]
| LaTeX-electric-left-right-brace is a variable defined in ‘latex.el’.
| 
| Its value is t
| Original value was nil
| 
| If non-nil, insert right brace with suitable macro after typing left brace.
| 
|   You can customize this variable.
| 
`----

Best, Arash
