Väitöskirjan nimi on "Fabrication of Optoelectronic Devices with Two-dimensional Layered Materials and Their Heterostructures"

The rising requirements for broadband, highly efficient, and integrable photonic devices compel researchers around the world to find proper material candidates to complement silicon technology. Graphene and transition metal dichalcogenides (TMDCs), which belong to van der Waals materials, have drawn unprecedented attention due to the new applications enabled by their prominent physical properties. Especially in the fields of photonics and optoelectronics, two-dimensional (2D), layered materials offer several advantages compared with traditional materials.

This thesis introduces 2D layered materials-based photonics devices, such as photodetectors and modulators. To achieve the goal, the corresponding fabrication methods, for example, exfoliation, transfer, pattern generation, dry etching and metal deposition are discussed in detail.

This dissertation offers an attractive way for both theoretical investigation and practical applications utilizing few-layer 2D layered materials, as well as paving a new way for novel, high-performance optoelectronics devices.
