Popular Summary Hybrid halide perovskites show impressive performance for optoelectronic applications, which raises key questions on the direct/indirect nature of the bandgap, their unexpected defect tolerance, and physical mechanism of bright luminescence. Combining theory and experiment, the authors show that the nature of the bandgap of hybrid halide perovskites spatially varies from a more direct surface region to a slightly indirect bulk.

Finally, the experimentally obtained μ e is compared with the calculated one. Figure 8 shows the temperature dependence of the experimental and calculated μ e. μ e is generally given by(1)where e is the elementary charge, ⟨ τ ⟩ is the average scattering time, and m ∗ is the effective mass.

Figure 2 shows the process for the sample preparation. CVD films were deposited on the Ib diamond substrates synthesized by high-pressure and high-temperature (HPHT) conditions, using microwave ( μ-wave) plasma. The μ-wave power of 750 W from the klystron was injected into the sample holder settled in the quartz tube, with flowing mixed CH 4/H 2 gases of 0.05% ratio, resulting in the sample temperature during deposition being kept at 800 °C. Deposited film thickness was 1.3 μm.
