Definitions
- the present invention relates to a wavelength tunable light emitting device and a method of manufacturing the same, and more particularly, to a wavelength tunable light emitting device using a magnetic moment inside a semiconductor iron silicide ( ⁇ -FeSi 2 ) and a method of manufacturing the same.
- a ferromagnetic metal is used for an electrode because a magnetic field needs to be applied to an active layer of the optical device even when an external magnetic field is removed.
- the magnetic field continues to be applied in the active layer even after the external magnetic field is removed, so that it seems that a wavelength tunable light emitting device can be produced by current injection. There's a problem.
- the barrier layer that separates the ferromagnetic metal electrode from the active layer is only about 0.1 m apart, the magnetic field applied to the active layer by the magnetic moment in the ferromagnetic metal electrode will be extremely small. Need to be thin. However, when the barrier layer is thin, electrons and holes in the active layer are susceptible to non-radiative recombination centers at the interface between the ferromagnetic electrode and the barrier layer. Therefore, electrons and holes in the active layer disappear without emitting light.
- G aM nAs is a direct transition type semiconductor having a magnetic moment. This is one in which several percent of the Ga atoms in GaAs are replaced by Mn atoms, which are transition metals having a magnetic moment, and a magnetic moment due to Mn exists inside. However, due to the difference in atomic radius between Ga and Mn, GaMnAs is greatly distorted and is not suitable for an active layer of a light emitting device. Disclosure of the invention
- the present invention eliminates the above-mentioned problems and achieves stable characteristics as an active layer of a light-emitting element by using a direct transition type semiconductor having a magnetic moment as a semiconductor itself as an active layer, thereby reducing crystal distortion.

(A) the step of embedding the non-doped Si layer into a single crystal by deforming the Fe-Si 2 into a spherical shape; and (d) growing the Si layer of the second conductivity type by Si molecular beam epitaxy. And embedded in the S i -P n junction depletion layer with ⁇ — F e S i 2 .
- the number of atoms is 1/10 to 1/100 of the number of Fe atoms deposited at the time of the Fe deposition.
- the magnetic impurities are added.
- FIG. 1 is a schematic view of a semiconductor light emitting device showing an embodiment of the present invention.
- FIG. 2 is a schematic view illustrating a process for manufacturing a semiconductor light emitting device according to an embodiment of the present invention.
- a semiconductor iron Shirisai de is a direct transition type semiconductor bandgap 0. 83 e V as the active layer of the semiconductor light emitting element (P- F e S i z) .
- ⁇ I FeSi 2 will be taken as an example of a semiconductor silicide, and an embodiment will be described.
- the metal and Si are commonly linked by a covalent bond, so the following method can be applied to semiconductor silicides other than ⁇ -FeS ⁇ 2 .
- FIG. 1 is a schematic diagram of a semiconductor light emitting device showing an embodiment of the present invention
- FIG. 2 is a schematic diagram showing a manufacturing process of the semiconductor light emitting device showing an embodiment of the present invention.
- 1 is an n-type (first conductivity type) Si substrate
- 2 is a spherically deformed active layer /? — FeSi 2
- 3 is a non-doped Si layer
- 4 is P Type (second conductivity type) Si layer
- 5 is a positive electrode
- 6 is a single electrode.
- P-type S i layer 4 is carried out by simultaneously irradiating the metaborate (HB0 2) when S i molecular beam Epitakisharu growth.
- Carrier concentration of the P layer may be adjusted by the ratio of S i and HB0 2 deposition rate.
- the deposition rate of 0. 4 AZS of S i by setting the K Nudsen cell temperature of metaborate (H BO z) and about 40 (TC, Kiyaria concentration of P-type S i layer 4 is about 1 0 ' 8 cm— 3.
- Si by molecular beam epitaxy, it is possible to embed a direct-transition semiconductor? FeSiz (2 ") in the Si-pn junction depletion layer. Can be.
- the diameter of the embedded ⁇ -1 F e S i 2 (2 ") depends on the thickness of the ⁇ 1 F e S i 2 film 2 that grows first.
- a ball with a diameter of about 90 nm is formed because the surrounding iron silicide gathers when it becomes spherical, and the diameter of the sphere is much greater than that of a film-like iron silicide. Also, as the film thickness decreases, the diameter of the ball decreases.
- the magnetic impurities are added simultaneously with the deposition of Fe atoms during the growth of the first FeS i 2 film, and the number of Fe atoms in F e S i z It can be added by evaporating a few% (10 2 ° or more per lcm 3 ).
- the optimum growth temperature is almost on the Si substrate. This is the substrate temperature when growing. Even when Mn is added by 17% of the number of Fe atoms, epitaxy can be achieved at 470'C. At this time, the amount of Mn is determined by the ratio of the deposition rate of 1? 6 and ⁇ 11. When 6 deposition rate 0. 1 A / s, configuring and about 850 hands Kn Udsen cell temperature of Mn, Mn added amount is 1 0 2 ° about per 1 cm 3. Will now be described the measurement of? One F e magnetic transport properties of S i 2.
- Electrode was formed by I n the 9 one F e S i 2 film having a thickness of 2 0 0 0 A, to measure the magnetic transport properties at 6 Tanhari method.
- the magnetic moment is small, it can be increased by adding another transition metal.
- semiconductor silicides originally have a very large number of transition metal atoms, and since the atomic radii are close to those of other magnetic metals, even if they are added in large amounts, they are hardly distorted. Therefore, even after the addition of the magnetic metal, it can be used as an active layer of a light emitting device.
- the active layer is magnetized by applying a magnetic field from the outside, so that the emission wavelength can be changed after the device is manufactured. Further, the changed emission wavelength can be maintained even after the removal of the external magnetic field.
- Semiconductor silicides contain a large number of transition metal atoms.Because their atomic radii are close to those of other magnetic metals, even when a large amount of transition metal atoms are added, the crystal distortion is small, and they are stable as active layers in light emitting devices. Properties can also be retained.
- the shift of the emission wavelength due to the application of an external magnetic field can be stably maintained even after the magnetic field is removed.
- variable wavelength light emitting device is suitable as a light emitting wavelength conversion device capable of multiplex optical communication, and is effective as a component for transmitting and receiving large amounts of information such as images at high speed.
