... emission techniques are also explored in detail in their respective chapters. Active photon probing takes advantage of the interactions of a scanned photon beam with an IC. For photon energies greater than the indirect band gap of silicon (≥ 1.1eV or wavelength ≤ 1100nm) electron-hole pairs are...
