Effect of the channel shape on the nano-scale carrier transport is studied by using the ensemble Monte-Carlo - molecular dynamics method (EMC/MD). Carrier transport in hone-shaped asymmetric channels which widen from source to drain sides is simulated by comparing that in the conventional straight channels. The obtained conductance of the horn-shaped channels is larger than that of the straight channel, as a result of the enhancement of the carrier mobility in the hone-shaped channel. This can be attributed to two reasons: the collimation effect of the asymmetric channel peculiar in the quasi-ballistic carrier transport regime, and the suppression of carrier-carrier interaction due to widening of the channel.
