摘要： A method for generating coordinate signals in conjunction with a surface of a field emission device having a cathode plate 2 coupled to an anode plate 32 comprises the steps of providing a first ultrasonic wave packet to the anode plate 32, receiving with a stylus 30 positioned proximate to the anode plate 32 the first ultrasonic wave packet, and then transmitting to the anode plate 32 with the stylus 30 a second ultrasonic wave packet responsive to the first ultrasonic wave packet. Next, receiving from the anode plate 32, with a plurality of piezoelectric point elements 44, the second ultrasonic wave packet, and then determining an x-position and y-position 35 of the stylus 30 responsive to the received second ultrasonic wave packet.

摘要： The improved method for microscopic measurement of electrical characteristics comprises a standard atomic force microscope (AFM). The AFM includes a pointed, conductively coated tip attached to one end of a softly compliant cantilever arm, also capable of conducting electricity. The other end of the cantilever arm is attached to the top of a piezo-electric z-axis driver which will raise and lower the cantilever arm as the AFM tip is scanned across the surface of a sample. A piezo-electric X-Y scanstage controller may also be provided and connected to the bottom of the z-axis driver. The X-Y scanstage is preferably capable of scanning the movement of the entire system including the Z-axis driver, cantilever arm and AFM tip.
