Internal field distribution and charge balance. a The capacitance-voltage (C–V) characteristics of a standard red device. b The C–V characteristics of a standard blue device. In the measurements, the modulating frequency is 100 kHz, and the modulating amplitude is 20 mV. Each device is measured before and after the lifetime test
