Abstract
A two-dimensional ultrahigh vacuum compatible positioner is presented. The positioner uses two piezoelectric inchworms which allow for motio ns of up to 1 cm viith a precision of 4 nm mounted at right angles to each other in order to give two dimensions of motion. Images of three- dimensional In0.3Ga0.7As islands in cross section are presented to dem onstrate the functionality of the positioner. It is found that motion towards the tip is smooth, while motion in the perpendicular direction is less smooth. (C) 1998 American Institute of Physics. [S0034-6748(9 8)03903-3].
