Pauli spin blockade and lifetime-enhanced transport in a Si/SiGe double quantum dot
Pauli spin blockade and lifetime-enhanced transport in a Si/SiGe double quantum dot
We analyze electron transport data through a Si/SiGe double quantum dot in terms of spin blockade and lifetime-enhanced transport (LET), which is transport through excited states that is enabled by long spin relaxation times. We present a series of low-bias voltage measurements showing the sudden appearance of a strong tail …
