  • Semiconductor photo-detecting device
    Patent number: 11935981
    Abstract: A photo-detecting device includes a first semiconductor layer with a first dopant, a light-absorbing layer, a second semiconductor layer, and a semiconductor contact layer. The second semiconductor layer is located on the first semiconductor layer and has a first region and a second region, the light absorbing layer is located between the first semiconductor layer and the second semiconductor layer and has a third region and a fourth region, the semiconductor contact layer contacts the first region. The first region includes a second dopant and a third dopant, the second region includes second dopant, and the third region includes third dopant. The semiconductor contact layer has a first thickness greater than 50 ? and smaller than 1000 ?.

  • Mobile terminal
    Patent number: 9667526
    Abstract: A mobile terminal includes: a peripheral interface having four terminals; an I2C interface; a first detection unit adapted to detect if an I2C device is inserted into the peripheral interface; and a first control unit adapted to, when the first detection unit detects there is an I2C device inserted into the peripheral interface, connect the I2C interface with the peripheral interface, such that the I2C interface is connected with the detected I2C device plugged in the peripheral interface. Accordingly, information exchange between mobile terminals and I2C devices can be achieved, thus adaptability of the mobile terminals can be expanded.
