A method for examining a specimen surface with a probe of a scanning probe microscope, the specimen surface having an electrical potential distribution. The method includes (a) determining the electrical potential distribution of at least one first partial region of the specimen surface; and (b) modifying the electrical potential distribution in the at least one first partial region of the specimen surface and/or modifying an electrical potential of the probe of the scanning probe microscope before scanning at least one second partial region of the specimen surface.

Methods and devices for examining an electrically charged specimen surface

Generating an image of an object and/or a representation of data about the object uses a particle beam apparatus. The particle beam apparatus comprises at least one control unit for setting a guide unit by selecting a value of a control parameter of the control unit. A functional relationship is determined between a first control parameter value and a second control parameter value depending on the predeterminable range of a landing energy of the particles. A desired value of the landing energy is set. The value of the control parameter corresponding to the desired value of the landing energy is selected on the basis of the determined functional relationship and the guide unit is controlled using the value of the control parameter corresponding to the desired value of the landing energy.
