A small bead under the edge of the last row of tile that butts up to the other floor. Be sure to remove the portion of laminate underlayment where the silicone is being used.
You don't need very much silicone, just enough to control some of the movement at the egde when you're not using an overlapping moulding.
Let me know if you have any other questions.
