Abstract: Sample loading device and electrostatic levitation apparatus. The electrostatic levitation apparatus includes a sample storage part including a rod-shaped sample standby part having an external diameter of a first diameter and a rod-shaped sample loading part having an external diameter of a second diameter and a sample cover part covering the sample standby part. The sample storage part has a loading bar inserting hole formed in its center. The loading bar inserting hole is formed through the sample standby part and is formed successively through a portion of the sample loading part. The sample standby part has sample storage vertical through-holes. The sample loading part has a single sample transfer vertical through-hole. The sample transfer vertical through-hole is formed on a surface where the sample storage vertical through-hole is viewed, penetrates the sample loading part, and is connected to the loading bar inserting hole.

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.
