Email After Interview Should I Send An Email After A Phone Interview And What Should I Say In It?

Should I send an email after a phone interview and what should I say in it? - email after interview

I just had a phone interview for a job that I really want to achieve. The investigator said he would speak to her supervisor, then remember, when they know that they are opening and when and where they will be people need to start. I really believe it would be wise to email and thank you for your time, but I do not know exactly what to say. Any help would be appreciated.
