Factors Affecting Terahertz Emission from InGaN Quantum Wells under Ultrafast Excitation

Muhammad Farooq Saleem, Ghulam Abbas Ashraf, Muhammad Faisal Iqbal +3

InGaN quantum wells (QWs) grown on c-plane sapphire substrate experience strain due to the lattice mismatch. The strain generates a strong piezoelectric field in QWs that contribut…
