Electron-matter interactions

• Electron-matter interactions accounts for
• Backscattering
• X ray emission
• Exposure dose modification
• CASINO

Example multilayers
3
Example grain boundary
4
Same exposure but different substrates

• YBCO/STO

• MgB2/Al2O3

CASINO simulations of the energy deposited by the
ebeam

• YBCO/STO
• YBCO 3.36 g/cm3
• STO 2.35 g/cm3

• MgB2/Al2O3
• MgB2 1.98 g/cm3
• Al2O3 1.90 g/cm3
