Donor dopants in oxide semiconductors are compensated not only by valuable electrons but also by other point defects, leading to a decrease in electric conductivity and infrared absorption. We demonstrate that the electron compensation mechanism in Ga doped ZnO nanocrystals can be promoted by photodoping. Unexpectedly, the electrons from photodoping are stable in the open air for months.

等离子体镓-ZnO纳米晶体的永久光掺杂

氧化物半导体中的施主掺杂剂不仅通过有价值的电子得到补偿，而且还通过其他点缺陷得到补偿，从而导致电导率和红外吸收的降低。我们证明，光掺杂可以促进Ga掺杂的ZnO纳米晶体中的电子补偿机制。出乎意料的是，来自光掺杂的电子在露天中稳定了几个月。
