A lab that shapes nanomaterials at the atomic scale to create new devices.
AboutAbout the lab
Shaping the nanoscale to break through the limits of devices
The Majima-Izawa Lab studies how to shape nanomaterials down to the smallest possible scale and bring out their functions.
The lab fabricates materials by combining state-of-the-art electron beam lithography with its own original electroless gold plating technique.
It develops nanopore sequencers that read DNA, single-molecule transistors, nanoscale gas sensors, and memory.
The lab is also advancing research on upconversion, which changes the wavelength of light, as well as organic EL (OLEDs) and organic solar cells.
Key terms
- Electron beam lithography
- A technique that draws the shapes of electrodes and circuits with nanometer-scale precision by irradiating a surface with a beam of electrons
- Nanopore
- A tiny hole a few nanometers wide. The behavior of molecules passing through it is read from changes in electric current
- Ferroelectric
- A material that retains electrical polarization even after the voltage is removed. It can be used for memory that does not lose data when the power is turned off

ResearchResearch themes
The lab shapes nanomaterials at the atomic scale by combining state-of-the-art electron beam lithography with its own original electroless gold plating. It carries out research and development on devices with practical use in mind, such as single-molecule transistors, nanopore DNA sequencers, nanoscale gas sensors, and organic EL.
*Illustrative imageSingle-molecule transistors
Combining a quantum dot a few nanometers across with spherical gold/platinum nanogap electrodes produces a transistor in which tunneling conduction is controlled by a gate. A transistor that uses a single 3 nm molecule as its semiconductor is already working.
*Illustrative imageNanoscale gas sensors
When resistive-type gas sensors are fabricated by electron beam lithography at sizes below 100 nm, their response and recovery become faster and their sensitivity increases. The lab develops devices such as hydrogen gas sensors based on palladium nanowires.
*Illustrative imageNanopore DNA sequencers
A nanopore sequencer reads single-stranded DNA passing through a hole a few nanometers wide from changes in ionic current. Making use of the property that electroless plating stops on its own, the lab aims to achieve DNA sequencing with metal nanopores.
*Illustrative imageTwo-dimensional ferroelectric memory
As a material for memory that retains data even when the power is turned off, the lab focused on α-In2Se3, which shows ferroelectricity at the atomic scale. By transferring this material onto electrodes with a gap length of 100 nm, it realized non-volatile memory based on in-plane polarization switching.
