What is your question? That you don't know what a function handle is? Or that you don't understand the error? The error tells you exactly what you need - a function handle. You created just a variable that is the result of an expression evaluated on the spot, assuming all those inputs are defined.

Your code should look something like,
fun = @(q) is * (exp((q * vd_f)/(k * tk)) - 1)
Here, the part inside the () after the @ should be the variable that you are integrating over.
