Oxide/metal/oxide (OMO) layer stacks are promising replacements for conventional transparent conductive oxides in thin-film photovoltaics. They can provide colouration of the solar cells by adjusting their thickness to optimised optical resonances. Green OMO multistacks were deposited on glass by subsequent sputtering of aluminium doped zinc...

Sub-micrometer thin-film transistors (TFTs) are realized using multi-level imprint lithography. Amorphous indium gallium zinc oxide (α-IGZO) TFTs with channel lengths as small as 0.7 μm, field-effect mobility of 10 cm2 V−1 s−1 and on/off ratio of circa 107 were integrated into a 1000-pixels per inch (ppi) TFT backplane array. The reduction of...

The thin-film-transistor (TFT) technology has attracted significant attention in account of the possibility to manufacture transistors on large and flexible substrates, at low processing temperatures and at a low cost. Next to the well-established amorphous silicon TFT technology used mostly for displays, the amorphous Indium-Gallium-Zinc-Oxide ...

Establishing the color of incident light is essential for many applications, such as machine vision, but generally requires either a dispersive component or multiple spectrally selective photodetectors. In contrast, here an incident spectrum is parametrized using a single broadband organic photodiode (OPD). This is achieved by exploiting the...

Aluminum doped zinc oxide (ZnO:Al) films were deposited by sputtering on borosilicate glass (sodium poor) and soda lime glass (sodium rich). These films were exposed up to 1032 hours of damp heat (85 °C/85 % relative humidity) to study the influence of among others the sodium content of the substrate on the ZnO:Al stability. A decrease in...

Thin-film transistors (TFTs) are the fundamental building blocks of today's display industry. To achieve higher drive currents and device density, it is essential to scale down the channel lengths of TFTs. To be able to fabricate short-channel TFTs in large volumes is also equally important in order to realize lower fabrication costs and higher...

With the advent of the Internet of things, wearable sensing devices are gaining importance in our daily lives for applications like vital signal monitoring during sport and health diagnostics. Amorphous indium gallium zinc oxide (a-IGZO) thin film transistors (TFTs) fabricated on flexible large-area substrates are a very interesting platform to...

Organic photodetectors (OPDs) have attracted much attention in recent years, due to their promise in large-area light sensing applications. Here, high-resolution slot-die-coated large-area bulk heterojunction organic photodiode (OPD) arrays are reported. The OPD uses a novel electron transport layer, indium gallium zinc oxide in combination with...

Electronic ratchets use a periodic potential with broken inversion symmetry to rectify undirected (electromagnetic, EM) forces and can in principle be a complement to conventional diode-based designs. Unfortunately, ratchet devices reported to date have low or undetermined power conversion efficiencies, hampering applicability. Combining...

Area-selective atomic layer deposition (ALD) of ZnO was achieved on SiO2 seed layer patterns on Hterminated silicon substrates, using diethylzinc (DEZ) as the zinc precursor and H2O as the coreactant. The selectivity of the ALD process was studied using in situ spectroscopic ellipsometry and scanning electron microscopy, revealing improved...

Elucidating the underlying principles behind band gap engineering is paramount for the successful implementation of semiconductors in photonic and optoelectronic devices. Recently it has been shown that the band gap of a wide and direct band gap semiconductor, such as ZnO, can be modified upon cocrystallization with amino acids, with the role of...

Atomic layer etching (ALE) provides Ångström-level control over material removal and holds potential for addressing the challenges in nanomanufacturing faced by conventional etching techniques. Recent research has led to the development of two main classes of ALE: ion-driven plasma processes yielding anisotropic (or directional) etch profiles...

Degradation rates and mechanisms for molybdenum back contacts and ZnO:Al front contacts exposed to damp heat were obtained from literature and experiments. It was found that molybdenum back contacts with a higher density and covered by a MoSe2 film are more stable than their low density, bare counterparts. For ZnO:Al front contacts various...

Copper-indium-gallium-di-selenide (CIGS) is the present record holder in lab-scale thin-film photovoltaics (TF-PV). One of the problems of this PV technology is the scarcity of indium. Multi-junction solar cells allow better spectral utilization of the light spectrum, while the required current generation per layer is much lower, allowing much...

Fume hoods are one of the most common types of equipment applied to reduce the potential of particle exposure in laboratory environments. A number of previous studies have shown particle release during work with nanomaterials under fume hoods. Here, we assessed laboratory workers’ inhalation exposure during synthesis and handling of CuO, TiO2...
