Oxide Thin Film Transistors

Dear Colleagues,

Thin-film transistors (TFTs) have been in extensive use as on/off switches and current-driving devices for various applications since the concept of TFTs was first reported. TFTs are considered one of the most important devices that controls each pixel in active-matrix flat panel displays (AMFPD). TFTs are widely used, not only in liquid crystals (LCs), but also in organic light-emitting diode (OLED) displays, from mobile displays to wide-sized displays. In particular, oxide TFTs have gained significant attention due to their superior performance compared to conventional amorphous Si (a–Si) TFTs, with high mobility, low off-current, and high transparency. Furthermore, oxide TFTs are very attractive for various sensor applications (bio, photo, gas, pressure, etc.) due to their merits, including high sensitivity and compatibility for large-area deposition. This Special Issue of the Applied Sciences, "Oxide Thin-Film Transistors", will cover recent advances in oxide TFT technology. The main topics are as follows: 1) device performance and stability, covering research into improving device performance and stability through material engineering, structural engineering, and post-/pre-treatment engineering of oxide TFTs. 2) Flexible and wearable oxide TFTs. This research deals with wavy, stiff, and neutralizing structures that can improve mechanical stability. 3) Various oxide TFT-based sensors and memory devices. This research includes advanced structures and materials that react to external energy sources such as light, bias, atmosphere, etc. 4) Various oxide materials. This research includes oxide materials such as hafnium oxide (HfO_x), zirconium oxide (ZrO_x), indium-zinc-oxide (IZO), indium-gallium-zinc-oxide (IGZO), indium-tin-zinc-oxide (ITZO), indium-tin-oxide (ITO), etc. for gate insulators, channels and electrodes.

Manuscript Submission Information

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 250 words) can be sent to the Editorial Office for assessment.

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. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
