Abstract

Photoluminescence (PL) mapping was utilized to investigate damage in β-Ga2O3 epilayers induced by 1064 nm laser pulses. The intensity and position of the intrinsic UV band were determined and plotted as a false-color image. Two types of damage were identified: circular damage and damage cracks. Circular damage shows lower UV PL intensity than the surrounding material with color centers in a “halo” around the damaged region. Damage cracks are aligned with the a and c axes and show higher PL intensity than undamaged material. Defects in the as-grown material were revealed by shifts in the UV band energy.

Abstract Image

激光损伤 β-Ga2O3 的光致发光绘图
利用光致发光(PL)绘图研究了 1064 nm 激光脉冲对 β-Ga2O3 外延层造成的破坏。确定了本征紫外波段的强度和位置,并绘制成假彩色图像。确定了两种类型的损伤:圆形损伤和损伤裂缝。圆形损伤显示出比周围材料更低的紫外可见光强度,颜色中心在损伤区域周围形成 "光晕"。损伤裂纹与 a 轴和 c 轴对齐,显示出比未损坏材料更高的紫外可见光强度。紫外波段能量的变化揭示了未加工材料中的缺陷。
