How do we use the scanning electron microscope
Drop onto silicon wafers, conditional can use infrared baking oven, or 50 degrees Celsius dry, to reduce organic film on sample surface imaging difficulties.
Most of the samples prepared by silicon wafer were dispersed on the surface of silicon wafer after the dispersion of nano particles. The test results and this kind of sample is silicon pretreatment, the main drying and sample dispersion and sample, the majority of small particle size, easy to agglomerate, take the solution can take the middle or upper clear liquid
After wiping with cotton wool, wash ear ball can be dried.Some of the words can be placed in alcohol solution ultrasonic cleaning, the effect is almost.
