=**WEEK OF SEPTEMBER 30TH**=

Today I learned so many things.I am so happy with that -color of the surface because i saw lucyenne's surface of gold which was yellow, i used to thought stm can recognize the colors of each material's surface. Also my graphite's surface shows orange color so that kind of shapes my thought stm can recognize the color. But actually stm cannot recognize the color it just recognize how far the surface if near to the tip. tip: how to change the color of surface? option->config color palette->choose a color -difference beteen nA and mV when i tried to move the surface near the tip it really didnt move closer and i know it didnt move closer enough because the screen shows black. So i told my instrcutor what happpend and she told me change the amp from 1nA to 2 or 3 nA. When i change the amps, the surface can move closer to the tip and there are more electrons as i increase the amp so it is eaiser to detect the surfhace when i increase the amps. But voltage is more complex concept. when i change the volatage basically it is same the the electrons are increasing but i better manipulate the amps rather than voltage. -can we always see better and clearer image when we increase the amp? not always. If distance between the tip and the surface is not appropriately small, the tip might run through the molecule so i may not be able to see the image. -When the tip run through the molecule, does it mean the tip crashed? I can say that but not always. when the molecules are really condensed, the tip might get crashed but when it is not think enough, the tip might scan the molecule.
