  • elektronmikroskoop, mille korral aatomteravik „ujub“ üle skaneeritava pinna (vt elektronmikroskoop, aatomteravik)
    Good to know
    • Aatomteraviku mõõtmed mõne aatomläbimõõdu suurusjärgus, horisontaalsuunas eraldusvõime ca 0,2 nm, vertikaalsuunas eraldusvõime ca 0,01 nm.
  • microscope which uses a probe with an "atomic micro-tip" floated, using superconducting levitation, over the surface being scanned (see: electron microscope, atomic microtip)
    Good to know
    • The top/surface is of order of atomic diameters so that the electron current obtained is through quantum mechanical tunneling; a horizontal resolution of ca 0.2 nm and a vertical resulution of ca 0.01 nm is obtained.

scanning tunneling microscope preferred
  • elektronmikroskoop, mida kasutatakse pindade pildistamiseks aatomitasandil
  • mikroskoop, milles skaneerib objekti pinda üliteravaks (üksikaatomini tipuks) söövitatud metallteravik
  • elektronmikroskoop, mille korral aatomteravik „ujub“ üle skaneeritava pinna
  • microscope for imaging surfaces at the atomic level
  • type of microscope used for imaging surfaces at the atomic level
skaneeriv teravikmikroskoop preferred
Usage examples
  • Skaneeriv teravikmikroskoop tunnetab pinda, kasutades äärmiselt teravat kompavat otsakut, mis suudab eristada 0,01 nm (10 pm) sügavuse eraldusvõimega suurusi, mis on väiksemad kui 0,1 nm, mis tähendab, et üksikuid aatomeid saab rutiinselt kujutada ja nendega manipuleerida.

scanning tunneling microscope preferred
Usage examples
  • Scanning tunneling microscope senses the surface by using an extremely sharp conducting tip that can distinguish features smaller than 0,1 nm with a 0,01 nm depth resolution. This means that individual atoms can routinely be imaged and manipulated.
