Enhanced Optical Microscope Image of a Hall-Bar Structure

Caption

An enhanced optical microscope image of a Hall-bar structure used to characterize transistor properties for devices made with ultraclean transferred contacts. The long radial lines, made from deposited gold, connect the small contacts at the center of the device to large probe pads for easy measurements.
