Brief Curriculum Vitae

Oliver Bernard Wright
Nationality: British

Prof. Wright in a stone lantern.
O. B. Wright initially specialized in low temperature solid state physics. Over the period 1982-1984 he published a detailed account of the thermoelastic effect in glasses at low temperatures—a modern version of a rubber band experiment in which the temperature change of the band is monitored on stretching.

After obtaining an industrial post he concentrated on applications of optics in sensor physics, in particular specializing in the use of ultrashort optical pulses for generating and detecting picosecond acoustic phonon pulses in thin films and multilayers. In 1992 he developed a related phonon pulse detection technique based on the measurement of picosecond surface motion. With this technique in 1994 he demonstrated how ultrafast electron diffusion could be probed in metals, and in 1998 he contributed to the development of a theory of this diffusion, establishing an analytical relationship between the electron energy relaxation time and the electron-phonon and electron-electron coupling strengths.

Focusing in 2001-2002 on semiconductors, he measured the shape of picosecond acoustic phonon pulses generated in gallium arsenide, and was involved in similar spectroscopic experiments on semiconductor quantum wells. In 2002 he also helped establish a method for watching ripples on crystals using ultrafast interferometry. He has also worked on the development of ultrasonic force microscopy and new local probe imaging techniques for thermal waves at high frequencies on nanometre length scales, as well as making contributions to the theory of the detection of phonon pulses in multilayers.

More recently he has been involved in extending picosecond ultrasonics to shear waves and to liquids, as well as spending time watching ripples travelling on phononic crystals and resonators.
