In addition, the semiconductor film can be flipped as it is transferred to its new substrate, making its other side available for more components. This doubles the possible number of devices that can be placed on the film.
By repeating the process, layers of double-sided, thin-film semiconductors can be stacked together, creating powerful, low-power, three-dimensional electronic devices.
These are single-crystal films of strained silicon or silicon germanium. Strain is introduced in the way they form the membrane. Introducing strain changes the arrangement of atoms in the crystal such that they can achieve much faster device speed while consuming less power.
By including the germanium without destroying the quality of the material, we can achieve devices with two to three orders of magnitude more sensitivity.”
That increased sensitivity could be applied to create superior low-light cameras, or smaller cameras with greater resolution.
