Dot-to-well transitions in InAs/InGaAs dots-in-a-well probed via photocurrent and electroluminescence spectroscopy
Hole states of InAs/InGaAs dots-in-a-well (DWELL0 are probed indirectly by observing inter-Quantum Well-QuantumDot (inter-QW-QD) transitions through photocurrent (PC) and low temperature electroluminescence (LT-EL) spectroscopy. We find multiple sharp peaks have spacing in the range of 10-20meV in...
