Description of Research
Merlin's research specialty is experimental condensed matter physics. His areas of expertise include various optical techniques and, in particular, spontaneous and impulsive (stimulated) Raman spectroscopy. His current interests focus on electronic and vibrational properties of III-V artificial semiconductor structures and the generation of coherent phonon fields using ultrafast laser pulses. Merlin and collaborators pioneered experimental work on Fibonacci superlattices, the quantum-confined Pockels effect and squeezed phonons. Other significant contributions include the earliest Raman studies of interface phonons, folded acoustic modes and shallow impurities in GaAs/AlAs heterostructures.
