The invention relates, inter alia, to a method for producing an electro-optical component () suitable for emitting electromagnetic radiation (), wherein in the method

Electro-optical component

A device including a locally modified buried first layer. A second layer is arranged on top of the first layer. The first layer includes at least one modified section and at least one unmodified section. The modified material of the locally modified buried first layer changes or induces mechanical strain in a portion of the second layer which is arranged above the at least one modified section. At least one nanostructure is placed on top of the second layer in an area, which is located above the at least one unmodified section of the first layer or adjacent thereto, said at least one nanostructure being formed by a strain-sensitive third material deposited on the locally strained second layer.

Layer assembly

The invention inter alia relates to a method of fabricating a layer assembly comprising the steps of: arranging a first layer on top of a carrier; arranging a second layer on top of the first layer; locally modifying the material of the buried first layer and providing at least one modified section in the first layer, wherein the modified material changes or induces mechanical strain in a portion of the second layer which is arranged above the at least one modified section; after locally modifying the material of the buried first layer, depositing a third material on top of the second layer, at least one characteristic of the third material being sensitive to the local mechanical strain in the second layer.
