Abstract: A digital adjusting signal for adjusting a multi-channel SQUID system is transmitted only to a control circuit module including a SQUID channel selected in an embodiment of the present invention and not transmitted to other modules. Accordingly, the digital adjusting signal is prevented from flowing into all SQUID adjusting channels to minimize noise generated by the digital adjusting circuit of the SQUID channel and to stably control the SQUID sensor without malfunction.

Abstract: The present invention relates to a method for manufacturing a GaAs semiconductor nanowire in a bottom-up type and, more particularly, to a method for manufacturing a vertically-aligned gallium arsenide semiconductor nanowire array in a large area by applying a voltage and a current from the outside using a metal thin film, which has been made through an economical method of fabricating a mesh-type metal thin film in a large area, as an anode such that holes (h+) are injected into a gallium arsenide substrate, thereby inducing a wet etching process continuously. The obtained vertically-aligned gallium arsenide semiconductor nanowire of a large area can be applied to fabrication of nanoelements, such as a solar cell, a transistor, and a light-emitting diode.

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.
