Abstract

In this letter, we present scalable and flexible diamond UV detectors. A 2-inch, 1-

$\mu $

m-thick diamond film is exfoliated from its heteroepitaxial silicon substrate and transferred to a soft PDMS substrate, forming the foundation for the flexible detector. Measurement under strains of 0%, 0.6%, and 1.2% reveals a decrease in the bandgap of diamond film from 5.31 eV to 5.18 eV and 5.06 eV, respectively. This strain-induced narrowing of the bandgap improves the responsivity of diamond detectors under UV illumination. The elastic strain engineering on diamonds, being simple and effective, provides a new route to improve the performance of diamond UV detectors, promising to accelerate the development of next-generation flexible diamond electronics.

应变增强响应的可伸缩柔性金刚石紫外探测器

在这封信中，我们提出了可扩展和灵活的金刚石紫外探测器。从其异质外延硅衬底上剥离2英寸，1 μ m厚的金刚石膜，并转移到软PDMS衬底上，形成柔性探测器的基础。在0%、0.6%和1.2%的应变下测量，金刚石薄膜的带隙分别从5.31 eV减小到5.18 eV和5.06 eV。这种应变引起的带隙变窄提高了金刚石探测器在紫外照射下的响应性。金刚石弹性应变工程简单有效，为提高金刚石紫外探测器的性能提供了一条新的途径，有望加速下一代柔性金刚石电子器件的发展。
