The Integrated Nanosystems Lab takes on the challenge of merging circuit engineering and device engineering to build integrated nanosystems that make the most of both. Its research spans semiconductor physics, circuit theory, information science, nonlinear theory, and neuroscience. After understanding the properties of new nanomaterials and devices, the lab designs circuits and information processing systems matched to their characteristics. Together with the Integrated Architecture Lab, it forms the Advanced LSI Engineering research group (LALSIE), promoting industry-academia and inter-university collaboration.

The Integrated Electronic Devices Lab studies selective-area growth and nanowire growth of III-V compound semiconductors by metal-organic vapor phase epitaxy (MOVPE). The lab covers the whole chain of work in one continuous line, from growing new materials to three-dimensional processing technology, device applications, and integration technology. By controlling the behavior of electrons and light with heterostructures of semiconductor nanowires, the lab aims to integrate high-performance, low-power switching circuits and highly functional optical devices. The lab is one of the labs of the Research Center for Integrated Quantum Electronics.

The Electronic Materials Lab studies electronics technology, including nanoelectronic materials, to create new electronic and optical functions. The lab seeks to understand how electrons and light behave in semiconductor nanoelectronic materials from the perspectives of both electronic engineering and condensed matter physics. Based on this understanding, the lab makes energy-saving light-emitting diodes, lasers, and photodiodes, and explores new devices for optoelectronic information conversion. The lab also works on simulation of the plasma used to integrate these devices.

The Nanoelectronic Devices Lab studies "spintronics," which makes use of both the charge and the spin of electrons. The lab freely controls the spin state of electrons in various materials, such as ferromagnets and semiconductors, to create devices with new functions. Using half-metals, ferromagnets in which spin direction is 100% aligned, the lab works on technologies leading to next-generation ultra-high-capacity, ultra-low-power memory and logic circuits. Toward quantum information devices that use spin, the lab also investigates the properties of electron spins and nuclear spins in semiconductors.

The Optoelectronics Lab studies quantum optics and quantum information, as well as nonlinear optics and optical information processing. Making use of the "quantum nature of light," the lab works on unconditionally secure quantum cryptographic communication, quantum computers that process enormous amounts of data, and quantum measurement with extreme sensitivity. Focusing on the "wave nature of light," the lab also handles optical information processing technologies such as ultra-high-capacity optical communication, optical phase conjugation, and super-resolution image processing. Its goal is breakthroughs that greatly change society, beyond what steady incremental improvements can reach.

The Nano Material Properties Engineering Lab aims to realize highly functional, high-performance devices using inorganic nanomaterials. Beyond making individual devices, the lab studies everything in one integrated effort: materials, devices, process development, and machine learning for data analysis. Applications are wide-ranging, including wearable health monitoring systems, electronic skin, IoT, plant health monitoring, and VR/AR. Undergraduate students also get to take part in international conferences and write papers in English, with the aim of training researchers and engineers who feel no barrier with English.

The Advanced Nano-Electronic Materials Lab studies new electronic materials using "epitaxial growth," in which semiconductor crystals are built up layer by atomic layer. When materials reach the nanometer scale, they show properties different from those they have at visible sizes. Building on molecular beam epitaxy, the lab makes semiconductor materials such as "nanowires," needle-shaped crystals that take advantage of these size effects. The lab was founded in April 2022, and its master's and doctoral students actively present at international conferences and write papers.

The Functional Communication and Sensing Lab studies systems, circuits, and devices for information communication and sensing, aiming to realize an IoT society. It works on devices that handle terahertz waves using low-cost CMOS technology, circuits that run on very little power, and intelligent sensing technology that also relates to human sensibility. In the device group, for power devices that must be highly efficient to save energy, the lab fabricates and evaluates the interface between gallium nitride (GaN) and insulating films (the MOS interface), and studies how to establish methods to control it.

The Functional Thin Film Materials Lab (Ohta Lab) studies new devices made from thin films of functional oxides. From oxides that have traditionally been treated as ceramics, the lab grows high-quality thin films with atomically flat surfaces and brings out their inherent properties. The lab works on three topics: "thermal transistors" that switch heat flow on and off, oxide thermoelectric materials that convert heat into electricity, and transparent oxide transistors. The lab conducts joint research with overseas universities, including Pusan National University in South Korea.

The Organic Quantum Photonic Devices Lab studies how electrons transition within materials and how materials interact with light. Through fundamental research that aims to understand these mechanisms from the ground up, the lab pursues research that leads to next-generation organic optoelectronics. The lab was launched in April 2025 and is run jointly by faculty members with different areas of expertise.
