I often use gschem to create publication quality circuit diagrams. See this 
for example:

http://www.ire.pw.edu.pl/~wkazubski/Wzmacniacz-RC

 In such cases indexes in subscript are often used. They are more readable 
than in standard text. For example load resistance RL may be confused with R 
times L, especially if used in a formula.
In the paper above I made subscript by manually placing smaller text in proper 
place.
