A resonant tunneling device includes a first two-dimensional semiconductor layer (131) including a first two-dimensional semiconductor material, like a transition metal dichalcogenide (TMDC or TMD), a first insulating, preferably also a two-dimensional, layer (140), on the first two-dimensional semiconductor layer; and a second two-dimensional semiconductor layer (132) on the first insulating layer and including a second two-dimensional semiconductor material of a same kind as the first two-dimensional semiconductor material. The substrate (110) may comprise a back gate and the two-dimensional semiconductor layers are connected to first and second electrodes (171, 172), which may comprise graphene (150 in Fig. 13).

A thermoelectric structure that may be included in a thermoelectric device may include a thin-film structure that may include a plurality of thin-film layers. The thin-film structure may include Tellurium. The thin-film structure may be on a substrate. The substrate may include an oxide, and a buffer layer may be between the substrate and the thin-film structure. The thermoelectric structure may be manufactured via depositing material ablated from a target onto the substrate. Some material may react with the substrate to form the buffer layer, and thin film layers may be formed on the buffer layer. The thin film layers may be removed from the substrate and provided on a separate substrate. Removing the thin-film layers from the substrate may include removing the thin-film layers from the buffer layer.

A pellicle configured to protecting a photomask from external contaminants may include a metal catalyst layer and a pellicle membrane including a 2D material on the metal catalyst layer, wherein the metal catalyst layer supports edge regions of the pellicle membrane and does not support a central region of the pellicle membrane. The metal catalyst layer may be on a substrate, such that the substrate and the metal catalyst layer collectively support the edge region of the pellicle membrane and do not support the central region of the pellicle membrane. The pellicle may be formed based on growing the 2D material on the metal catalyst layer and etching an inner region of the metal catalyst layer that supports the central region of the formed pellicle membrane.

A multilayer structure includes a first material layer (L10), a second material layer (L20), and a diffusion barrier layer (B10). The second material layer is connected to the first material layer. The second material layer is spaced apart from the first material layer. The diffusion barrier layer is between the first material layer and the second material layer. The diffusion barrier layer may include a two-dimensional (2D) material. The 2D material may be a non-graphene-based material, such as a metal chalcogenide-based material having a 2D crystal structure. The first material layer may be a semiconductor or an insulator, and the second material layer may be a conductor. At least a part of the multilayer structure may constitute an interconnection for an electronic device.
