Above a surface pressure threshold ,
we detect a buckled state in the low temperature solid phase of a
phospholipid monolayer spread at the air-formamide interface. Stable ripples are observed with a Brewster angle
microscope, and light scattering provides measurements
mNm-1,
wavelength
m and amplitude ξ of a few nm for the deformation. A model, coupling the monolayer thickness and elongation, and consistent with the monolayer
texture, is also presented.
