PAM-XIAMEN offers silicon ingot with FZ Intrinsic undoped, MCC lifetime (Minority Charge Carrier Lifetime) more than 1000Ωcm. An intrinsic(pure) semiconductor, also called an undoped semiconductor or i-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself [...]
PAM XIAMEN offers Yb YAG Ytterbium (Yb) doped Yttrium Aluminium Garnet Laser Crystal. Ytterbium – Yb:YAG is a very promising laser crystal and is more suitable for diode-pumping than the commonly used Nd-doped YAG crystals.
