Abstract
The two-dimensional plasmon of an $n$ inversion layer of (100) $p$-type Si is observed at a fixed wave vector as a function of electron density. The position, width, and strength of the resonance agree with existing theory at electron densities \ensuremath{\gtrsim}${10}^{12}$/${\mathrm{cm}}^{2}$. At lower densities, the resonance position is below the predicted value, implying a substantial increase in the electron mass.
