摘要:
The present disclosure relates to a semiconductor nanostructure. The semiconductor nanostructure includes a substrate and at least one ridge. The substrate includes a first crystal plane and a second crystal plane perpendicular to the first crystal plane. The at least one ridge extends from the first crystal plane along a crystallographic orientation of the second crystal plane. A width of cross section at a position of half the height of the at least one ridge is less than 17 nm. The semiconductor nanostructure is a patterned structure which can lead to generate a quantum confinement effect, such that the impurity scattering phenomenon is reduced.

A ferroelectric film includes a plurality of ferroelectric nanodomains configured in a regularly staggered fashion. The ferroelectric film has a quasi 2-dimensional configuration and is comprised of a ferroelectric material. A method for forming a ferroelectric film is also provided. A ferroelectric film comprised of a ferroelectric material is prepared. The ferroelectric film has a quasi 2-dimensional configuration and defines a direction that is normal to the quasi 2-dimensional configuration. An electric field along the normal direction is applied to the ferroelectric film, thereby the ferroelectric film having an array of ferroelectric nanodomains configured in a regularly staggered fashion is obtained.

An exemplary spin-polarized electron source includes a cathode, and a one-dimensional nanostructure made of a compound (e.g., group III-V) semiconductor with local polarized gap states. The one-dimensional nanostructure includes a first end portion electrically connected with the cathode and a second end portion located/directed away from the cathode. The second end portion of the one-dimensional nanostructure functions as a polarized electron emission tip and is configured (i.e., structured and arranged) for emitting a spin-polarized electron current/beam under an effect of selectably one of a magnetic field induction and a circularly polarized light beam excitation when a predetermined negative bias voltage is applied to the cathode. Furthermore, a spin-polarized scanning tunneling microscope incorporating such a spin-polarized electron source is also provided.

Processes for making light to current converter devices are provided. The processes can be used to make light to current converter devices having P-N junctions located on only the top surface of the cell, located on the top surface and symmetrically or asymmetrically along a portion of the inner surface of the via holes, located on the top surface and full inner surface of the via holes, or located on the top surface, full inner surface of the via holes, and a portion of the bottom surface of the cell. The processes may isolate the desired P-N junction by etching the emitter, forming a via hole after forming the emitter, using a barrier layer to protect portions of the emitter from etching, or using a barrier layer to prevent the emitter from being formed on portions of the substrate.
