Dear Colleagues,
In the last 40 years, thin-film transistors (TFTs) have come a long way from potential electronic devices to being used in our smartphones. Advancements in TFTs have been achieved through technological improvements in the research and development of materials, processes, and devices.
From a materials perspective, semiconductors have been the main focus. Amorphous and polycrystalline materials have been investigated, from amorphous silicon and polysilicon to organic materials, oxide semiconductors, CNTs, and the recent development of perovskite and 2D materials. For dielectrics, SiO2 has been the main choice, but high-k dielectrics have also been considered. Ferroelectric dielectrics have also opened the way to other advanced applications. The materials used as the substrate have also changed with time, as nowadays flexible or even stretchable substrates are commonly investigated. In terms of processes, vacuum processes like sputtering and plasma-enhanced chemical vapor deposition (PECVD) have mostly been used for practical industrial applications. Nonetheless, non-vacuum processes, including but not limited to inkjet printing, spin-coating, spray coating, and roll-to-roll, have led to the possibility of devices with reproducible and high-mobility characteristics. In terms of devices, conventional TFT structures (staggered, inverted staggered, coplanar, and inverted coplanar) and other structures (like the Corbino TFT, dual gate, etc.) have been widely investigated to obtain devices with higher stability and higher mobility. More recently, hybrid solutions, like LTPO inverters, have been investigated for CMOS applications, and the development of technology computer-aided design (TCAD) has allowed us to better understand and strategize the development of circuits for larger electronics like active matrix organic light-emitting diodes (AMOLED). Finally, TFTs can also be used in bioelectronics or even in biomimicking (e.g., synaptic) devices.
In this paper, we invite the submission of manuscripts related to the most recent and newest approaches to TFT materials, processes, and devices that could reflect tomorrow’s applications. Full papers, communications, and reviews are welcome.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.
