| 摘要 |
<p>The present invention concerns a microscopic electromagnetic radiation transmitter or detector and a so-called near field probe (1) whose body takes the form of a polyhedron point and consists of a material which is at least partially permeable to electromagnetic radiation in the spectral region used. The polyhedron point is delimited by an imaginary base surface beyond which the substantial part of the body is continued to form a total probe body, which is not defined in greater detail. The polyhedron point has n side faces and edges leading to an acute point (2) are formed between adjacent side faces. According to the invention, at least two side faces of the body of the polyhedron probe (1) are coated with thin, electrically conductive layers which absorb some of the electromagnetic radiation in the spectral region used, preferably consist of materials such as aluminium, gold or silver and are less than 0.2 mu m thick. The front part of the polyhedron point (2) is also coated with the material used, resulting in an efficient near field probe with comparatively high resolution in optical near field scanning microscopy, simultaneous scanning tunnel microscopy also being possible with the same point.</p> |
