Formation of liquidlike and crystalline structures in dusty plasmas

A study of the strongly coupled dusty plasma was carried out over a wide ra nge of plasma pressures and temperatures. The plasma was investigated under conditions of low-pressure inductively coupled radio frequency gas dischar ge and under thermal plasma conditions at atmospheric pressure. The plasma was also formed from positively charged dust grains in the presence of a fl ux of ultraviolet photons. The results of experimental observations of orde red dust structures are reported, and the characteristic features of the du st structures and the conditions for their appearance are discussed.
