The development of surface chemistry ensures that the silicon channel is indeed modulated by the photovoltage of the colloidal quantum dot instead of being unresponsive owing to self-pinning; the colloidal quantum dot photogate directly modulates the width of the depletion region in the bulk of the channel.

Voyager 1, launched in 1977, is now at the very limit of the solar system; currently negotiating the heliosheath depletion region – the final frontier before raw interstellar space.

Voyager is in a new region of space, and now that place has a name Say hello to a brand new bit of the solar system, brought to you by that intrepid traveller Voyager 1: the heliosheath depletion region.

Scientists working on Voyager are calling this place the “heliosheath depletion region”.

The heliosheath depletion region has two of those three.
