The Mott transistor capable of operating at a room temperature can be realized by using a self-organized nanoparticle array for the channel portion. The nanoparticle used in the present invention comprises metal and organic molecules, and the size thereof is extremely small, that is, about a few nm. Therefore, the charging energy is sufficiently larger than the thermal energy k<SUB>B</SUB>T=26 meV, and the transistor can operate at a room temperature. Also, since the nanoparticles with a diameter of a few nm are arranged in a self-organized manner and the Mott transition can be caused by the change of a number of electrons of the surface density of about 10<SUP>12 </SUP>cm<SUP>-2</SUP>, the transistor can operate by the gate voltage of about several V.
