• The effect of the plasmon and/or the acoustic plasmon on superconductivityis investigated in two-subband systems in MOS inversion laycrs by' nunaericalsolutions of the gap equation in the weak-coupling theory of supercc>nductivity,in which the effective interactions are evaltuated in the RPA. When the carrierconcentration of the system is low, it is shown that the p]asm.on pla)rs the mainrole in the superconductivity, while when it is high, the primary c?ontributioncomes frona the acoustic plasmon. Several criteria to get a high transition term-perature are obtained. The Si(100)/Si0. systena is predicted to show the super-conducting behavior at the temperatures around l mK.
