Ultraviolet nanosecond laser ablation of polyimide with thermal and nonthermal effects near threshold fluence
Autor: ChangSoon Han, Muhammad Aleem Zahid, Byungwoo Lee, Jae-Yong Oh, Youngkuk Kim, Junsin Yi
Publikováno v: Journal of Laser Applications. 34:032004
Typically, a 355 nm laser is not sufficient for inducing photochemical ablation and leads to photothermal effects such as melting and recasting. Consequently, most previous studies on the irradiation of polyimide (PI) with such lasers have focused on

Effectiveness of Iodine Termination for Ultrahigh Efficiency Solar Cells as a Means of Chemical Surface Passivation
Autor: Youn-Jung Lee, Kyungsoo Lee, Junsin Yi, Youngmi Jo, Changsoon Han, Minkyu Ju
Publikováno v: Japanese Journal of Applied Physics. 51:09MA03
The use of iodine as a passivating agent for chemical modification of silicon surface is demonstrated. The measurement of carrier lifetime using microwave photoconductivity decay method shows an effective passivation with iodine treatment which is 5
