We study carrier-envelope-phase-sensitive (CEP-sensitive) photoemission from plasmonic nanoantennas excited with laser pulses of varying incident optical intensities. The CEP-sensitive current exhibits antiresonant-like features that we attribute to competing sub-optical-cycle bursts of photoelectrons.
