Thickness-Dependent Spintronic Terahertz Emission in MBE-Grown PtTe: From Semiconductor to Type-II Dirac Semimetal
Rahul Sharma, Sylvain Massabeau, Armando Pezo +13
Spintronic terahertz (THz) emitters have established themselves as among the most practical broadband THz sources available, yet their performance remains fundamentally limited by…
