The most interesting feature of an exciton is that it can be generated by and converted back into a photon within a short time (&lt;nsec). Thus, excitonic devices potentially bring great improvements to the speed of electronic\u2013optical (E\/O) conversion along with significant miniaturizations of E\/O converters. The major challenges for excitonic devices are finite exciton binding energy (Eex) and finite exciton lifetime. The small exciton binding energy of typical excitonic materials, such as GaAs, limits the device operation temperature below 125K. While, the exciton lifetime in such materials is less than a nanosecond, allowing excitons to travel only a small distance before it recombines. In this laboratory, we have developed an excitonic device with a new semiconducting material, (ZnO)x(InN)1-x (abbreviated as ZION), which has large Eex as well as large piezoelectric constant. The large Eex potentially enables excitonic devices that are operational at room temperature. Another advantage is the long exciton lifetime, allowing excitons to travel long distance before it recombines. The aforementioned excellent properties of ZION films and its QWs open a new avenue for studies toward the practical use of excitonic devices.<\/p>\n<\/div>\n<div class=\"lab_box\">\n<h3 id=\"lce\">Constructive Electronics Laboratory<\/h3>\n<p><img decoding=\"async\" class=\"alignright size-full\" src=\"\/e\/wp-content\/uploads\/lce-e.png\" alt=\"Constructive Electronics Laboratory\" \/><strong>Members : <\/strong>Assoc.Prof. Takeaki Yajima<\/p>\n<p class=\"link_outside\"><a href=\"https:\/\/con.ed.kyushu-u.ac.jp\/\">More Individual Lab Sites<\/a><\/p>\n<p class=\"key\"><strong>keywords : <\/strong>Semiconductor, Oxide thin film, Phase transition, Low-power circuits, Recurrent neural network<\/p>\n<p>The 21st century is the age of information.

We are also developing transformable drones that can operate in confined or complex environments, with the aim of performing tasks such as collecting data from disaster sites that conventional drones cannot.<\/p>\n<\/div>\n<div class=\"lab_box\">\n<h3 id=\"mrl\">Inorganic Functional Materials x Excimer Laser Laboratory<\/h3>\n<p><img decoding=\"async\" class=\"alignright size-full\" src=\"\/e\/wp-content\/uploads\/yabuta_lab_2026_e.png\" alt=\"Inorganic Functional Materials x Excimer Laser Laboratory\" \/><br \/>\n<strong>Members : <\/strong>Prof. Hisato Yabuta<\/p>\n<p class=\"link_outside\"><a href=\"https:\/\/mrl.ees.kyushu-u.ac.jp\/EN_Main.html\">More Individual Lab Sites<\/a><\/p>\n<p class=\"key\"><strong>keywords : <\/strong>Inorganic semiconductors, ferroelectric materials, oxide superconductors, excimer-laser annealing, pulsed lased deposition<\/p>\n<p>Today&#8217;s electronic devices use not only traditional materials, such as silicon for semiconductors, but also many newly discovered materials with functions that were previously unknown. For example, oxide materials like glass are used in smartphones and tablet PCs as semiconductors for transistors instead of silicon. Our research is focused on finding new inorganic materials, adding new functions and properties to them, and forming these as thin films to be used in modern devices. For this research, we use excimer lasers, which generate powerful ultraviolet beams, to synthesize new materials and process them to produce new functions.We are studying to make sure that these new materials and functions will be used in the next generation of devices.<\/p>\n<\/div>\n<div class=\"lab_box\">\n<h3 id=\"yoshida\">Applied Electromagnetic Energy Laboratory<\/h3>\n<p><img decoding=\"async\" class=\"alignright size-full wp-image-1613\" src=\"\/e\/wp-content\/uploads\/yoshida_lab_e.png\" alt=\"Applied Electromagnetic Energy Laboratory\" class=\"alignright size-full wp-image-1613\" srcset=\"https:\/\/www.isee.kyushu-u.ac.jp\/e\/wp-content\/uploads\/yoshida_lab_e.png 1299w, https:\/\/www.isee.kyushu-u.ac.jp\/e\/wp-content\/uploads\/yoshida_lab_e-800x706.png 800w, https:\/\/www.isee.kyushu-u.ac.jp\/e\/wp-content\/uploads\/yoshida_lab_e-1024x903.png 1024w, https:\/\/www.isee.kyushu-u.ac.jp\/e\/wp-content\/uploads\/yoshida_lab_e-768x678.png 768w\" sizes=\"(max-width: 1299px) 100vw, 1299px\" \/><br \/>\n<strong>Members : <\/strong>Prof. Takashi Yoshida \/ Asst.Prof. Hiromasa sasa<\/p>\n<p class=\"link_outside\"><a href=\"https:\/\/www.sc.kyushu-u.ac.jp\/~enlab\/index.html\">More Individual Lab Sites<\/a><\/p>\n<p class=\"key\"><strong>keywords : <\/strong>Magnetic nanoparticles, Magnetic particle imaging, High output power density motor, Superconducting motor<\/p>\n<p>We are developing novel medical systems and high-performance electrical machines based on \u201cmagnetism\u201d. \u201cMagnetism\u201d enables the contactless transfer of force and energy, and the contactless detection of magnetic signals without being affected by the human body.

In our laboratory, we are developing ultrasensitive magnetic sensors for detecting weak magnetic fields, and are aiming to apply these magnetic sensors to medical devices and nondestructive testing. Specifically, in medical devices, we are developing a magnetic imaging device for cancer using magnetic markers.
