Abstract: An electrostatic levitation crystal growth apparatus for a solution and a crystal growing method using the same. The apparatus may include an upper electrode, a lower electrode vertically spaced apart from the upper electrode, a power supply unit configured to apply a vertical electrostatic field between the upper electrode and the lower electrode, and a droplet dispenser configured to eject a solution into a region between the upper and lower electrodes and thereby to form a solution droplet. The solution droplet may be maintained in a charged state and may be electrostatically levitated against the gravity exerted thereon, by the vertical electrostatic field. The solution droplet may be evaporated in the electrostatically levitated state, and a solute dissolved in the solution may be grown to form a crystal.
