Abstract Waveguide-integrated Ge/Si heterostructure avalanche photodetectors (APDs) were designed and fabricated using a CMOS-compatible process on 8-inch SOI substrate. The structure of the APD was designed as separate-absorption-charge-multiplication (SACM) using germanium and silicon as absorption region and multiplication region, respectively. The breakdown voltage (Vb) of such a device is 19 V at reverse bias and dark current appears to be 0.71 μA at 90% of the Vb. The device with a 10-μ length and 7-μ width of Ge layer shows a maximum 3-dB bandwidth of 17.8 GHz at the wavelength of 1550 nm. For the device with a 30-μ-length Ge region, gain-bandwidth product achieves 325 GHz.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
