Abstract
, significantly higher than those of previously reported pristine Bi QD and Te NS-based PDs. The PDs are further demonstrated to have excellent self-power capability and long-term stability over 30 days. Additionally, the obtained 786 fs pulse output signal in the telecommunications band reveals the great potential of Bi/Te for ultrafast photonic devices. It is believed that such VA/VIA binary heterostructures provide opportunities for developing multifunctional optoelectronic devices for nano-science applications.
