We study the instability of the traveling waves ofa sixth-order parabolic equation which arises naturally as a continuum modelfor the formation of quantum dots and their faceting. We prove that sometraveling wave solutions are nonlinear unstable under 4 perturbations. Thesetraveling wave solutions converge to a constant as →∞
