That is the defined function in my Matlab Function Block: The Result should be a curve the the Time t should be a interval e.g. from 0 to 10 How can I enter the time?
function i8_20 = fcn(t) %#codegen
ipeak=10000;
i8_20 = (ipeak/0.616)*sin(0.12*10^6*t)*exp.(-(t/(24.1e-06)));

You can use the clock block to get the time. http://www.mathworks.com/help/simulink/slref/clock.html

My stop time is 2 sec. Now, if i make use clock block it just gives me two steps. I want to reduce its step time to 100usec. How should I do it?

you could try it with a triggered subsystem, which is triggered with a pulse generator with a period time of 100us
