    "abstract": "Dusty plasmas consists of an ionized gas containing small (usually negatively\ncharged) particles. Dusty plasmas are of interest in both astrophysics and\nspace physics as well as in research in plasma processing and nanofabrication.\nIn this work, the formation of plasma crystals confined in an external\none-dimensional parabolic potential well is simulated for a normal experimental\nenvironment employing a computer code called BOX_TREE. Such crystals are\nlayered systems, with each layer a two dimensional lattice composed of grain\nparticles. The number of layers is dependent upon the external potential\nparameter. For constant layer number, the intralayer structure transits from a\nsquare lattice to a hexagonal (triangular) lattice as the confining potential\ndecreases. For hexagonal lattices, both hcp and fcc characteristics were found\nbut hcp structures dominate. The relative thickness of the system was also\nexamined. The results were compared with previous experimental and theoretical\nresults and found to agree.",
