|Outline of Final Research Achievements
Owing to miniaturization and high integration in semiconductor devices, the integrated heat and its fluctuation causes degradation of performance and precision. To solve it, we aim to develop a new material that can electrically control heat flow. In this work, we focused on spin ladder materials (La5Ca9Cu24O41) whose heat carrier is a unique particle, magnon. We proposed and fabricated a prototype for the dynamic control and demonstrated that magnons and their thermal conduction can be electrically controlled by an application of voltage via an ionic liquid.
