My previous NSERC Discovery Grant yielded exceptional progress in: (a) Making so-called semiconductor nanowire (NW) heterostructures (NWHs), with lengths/widths ~1/10th and ~1/1,000th of the thickness of a human hair (i.e., where the NW material changes along its length to another semiconductor, or where it is clad in a shell of another semiconductor). Such NWHs enable unprecedented control over where electrons reside; (b) Realising NWs from semiconductors which also showed magnetic properties, well above room temperature - an important precursor for so-called spintronics, where both electron charge and spin are used for information processing (IP); and (c) A first demonstration of a hybrid device mating a high temperature superconductor (HTSC) to a thin film semiconductor, showing, for the first time at elevated temperature, how so-called Cooper pairs could be efficiently injected into a thin film semiconductor, with promise for a future quantum computer. My current objective is to harness this work to explore the completely novel field of so called hybrid field effect transistors (FETs) to enable injection/control of; (a) Cooper pairs in a NWH to generate entangled photon pairs (EPPs); (b) spin polarised electrons for a so-called NWH spin-FET and (c) light induced charge, for single photon detection (SPD). The work should contribute to uncovering fundamental science (e.g., testing of Bell inequalities and advancing work on the unobserved new particle, the Majorana Fermion) and significantly furthering practical implementation of IP technologies (e.g., toward quantum cryptography and low power spintronics for information storage/manipulation).The research will offer an exceptional opportunity for training of 4 PhD students while advancing our world class leading edge research program in NWH science.

我之前的NSERC发现基金在以下方面取得了非凡的进展：(a)制造所谓的半导体纳米线（NW）异质结构（NWHs），其长度/宽度约为人类头发厚度的1/10和1/ 1000（即NW材料沿着其长度变化到另一种半导体，或者它被包裹在另一种半导体的外壳中）。这样的nwh可以前所未有地控制电子的位置；(b)从还显示远高于室温的磁性的半导体中实现NWs -这是所谓自旋电子学的重要前体，其中电子电荷和自旋都用于信息处理（IP）；(c)首次展示了将高温超导体（HTSC）与薄膜半导体结合在一起的混合装置，首次在高温下展示了如何将所谓的库珀对有效地注入薄膜半导体，这为未来的量子计算机带来了希望。我目前的目标是利用这项工作来探索所谓的混合场效应晶体管（fet）的全新领域，以实现注入/控制；(a) NWH中的库珀对产生纠缠光子对（EPPs）；(b)用于所谓的NWH自旋场效应晶体管的自旋极化电子和(c)用于单光子探测（SPD）的光感应电荷。这项工作应该有助于揭示基础科学（例如，贝尔不等式的测试和推进未观测到的新粒子，马约拉纳费米子的工作），并显著促进IP技术的实际实施（例如，用于信息存储/操作的量子密码学和低功率自旋电子学）。该研究将为培养4名博士研究生提供一个特殊的机会，同时推进我们在NWH科学领域的世界级前沿研究项目。
