In electron microscope test, tungsten electric needle, as an electron source, can interact with the sample surface to stimulate various physical and chemical information of the sample. This information includes morphology, composition, crystal structure, etc. By using tungsten electric needle as an electron source, higher resolution and higher quality images can be obtained. In addition, tungsten electric needle can also be used as a heater to heat the sample surface through electric current to achieve sample heating and property change. In some electron microscope tests, the sample needs to be heated to change its physical and chemical properties. At this time, tungsten electric needle can be used as a heater to heat the sample surface through electric current to achieve sample heating and property change. In addition, tungsten electric needle can also be used as a lead material to introduce current from the test instrument to the sample surface to achieve current transmission and control.
