This project is a fundamental science exploration of novel ways to guide quasiparticles known as excitons emerging in atomically thin (2D) semiconductors and their heterostructures, with the aim to demonstrate the control over fluxes of these hydrogen-like bosonic particles and therefore open a pathway to the study of excitons in controllable potential profiles. These studies are cornerstone to pioneer the on-chip bosonic counterpart of quantum electronics and novel macroscopic quantum states. At the same time the on-chip control of excitons dynamics and flow may offer radically new approaches to interface efficient photon-based signal communication to electron-based signal processing technologies. The main breakthrough sought by this PhD project will be to demonstrate an effective method to generate a controlled pressure able to displace charge neutral excitons in 2D materials This DTP studentship explores fundamental aspects of the physics of excitons in 2D systems which also underpin the EPSRC New Horizon "tuneable excitonic circuits" awarded to Prof Saverio RUsso (PI).

该项目是一项基础科学探索，旨在探索引导原子薄（2D）半导体及其异质结构中出现的准粒子（称为激子）的新方法，目的是展示对这些类氢玻色子粒子通量的控制，从而为研究可控电位剖面中的激子开辟一条途径。这些研究是开创片上玻色子对应物量子电子学和新的宏观量子态的基石。同时，芯片上激子动态和流动的控制可以为基于光子的高效信号通信和基于电子的信号处理技术提供全新的接口方法。该博士项目寻求的主要突破将是证明一种有效的方法来产生能够取代二维材料中的电荷中性激子的可控压力。该DTP学生探索二维系统中激子物理学的基本方面，这也支持EPSRC新视野“可调谐激子电路”授予Saverio RUsso教授（PI）。
