Приведены результаты моделирования для случая двух близкорасположенных точечных зарядов при различных соотношениях диаметра чувствительного элемента сканирующего зонда Кельвина и зазора «зонд-образец». Показано, что наиболее эффективным путем повышения разрешающей способности сканирующего зонда Кельвина является уменьшение расстояния между чувствительным элементом и поверхностью исследуемого образца при уменьшении амплитуды вибрации чувствительного элемента.</p></abstract><trans-abstract xml:lang="en"><p>A mathematical model of cylindrical shaped plane-ended scanning Kelvin probe output signal is proposed considering the case of an infinite plane sample's surface with local defects represented by dot charges. Modeling results were obtained for the case of two closely situated dot charges anddifferent combinations of scanning Kelvin probe tip's diameter and sample-to-probe gap. It was found that the most effective way to improve the lateral resolution of a scanning Kelvin probe is to reduce the sample-to-probe gap in line with the reduction of sensor's vibration amplitude.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>зонд Кельвина</kwd><kwd>разрешающая способность</kwd><kwd>метод изображений</kwd><kwd>электрический заряд</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Kelvin probe</kwd><kwd>lateral resolution</kwd><kwd>method of images</kwd><kwd>electric charge</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Klein, U.
