The resufts obtained show that PTPC permits to provide the resonance conditions for detecting polaron effects in the QW of the near-surface delta-layer. In combination with the planned experiments being in parallel magnetic field the PTPC effect allows to obtain new data on threshold interaction of 2D electrons with optical phonons. In our opinion the significant value of the polaron effects in our structures is related to the self-consistent potential profile of delta-layer QW. Unfortunately there is no theory of resonant intersubband polaron in such systems which does not permit to compare observed effects with calculations.
