The size of V pits varied from 57 to 250\u2009nm. Two different-size LEDs (10 and 300 \u00b5m) were fabricated with flip-chip structures. It was shown that at 4 A cm^\u22122, the forward voltages of 300 \u00b5m-size and 10 \u00b5m-size LEDs were in the range of 2.32\u20132.82 V and 2.23\u20132.53 V, respectively. Compared with the LEDs with small V pits, the LEDs with large V pits produced higher output power at the high current region (\u003e50 A cm^\u22122), but lower output power at the low current region (\u003c20 A cm^\u22122). The 300 \u00b5m-size LEDs displayed maximum external quantum efficiency (EQE) at 2 A cm^\u22122, whereas the 10 \u00b5m-size LEDs exhibited peak EQE at current densities\u2009\u2009\u226513 A cm^\u22122. For all samples, the electroluminescence (EL) wavelengths were blue shifted with increasing current density. Unlike the 300 \u00b5m-size LEDs, the 10 \u00b5m-size LEDs exhibited a large deviation in the light output, EQE, and EL wavelength. The 10 \u00b5m-size LEDs revealed larger S than the 300 \u00b5m-size LEDs. The backscattered electron (BSE) and monochromatic cathodoluminescence (CL) results showed that for all samples, V pits were unevenly distributed across the whole wafer. Based on the CL and BSE results, the effect of different V pit sizes on the performance of green micro-LEDs at the low current region is described and discussed.", "subitem_description_type": "Abstract"}]}, "item_10_description_5": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "\u30d5\u30a1\u30a4\u30eb\u516c\u958b\uff1a2021-01-23", "subitem_description_type": "Other"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "IOP publishing"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1088/1361-6463/ab52d0", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "This is an author-created, un-copyedited version of an article published in {Journal of Physics D: Applied Physics}.
