======================


       
      

**Superconducting Materials**

 

High Kinetic Inductance Superconductor

**Tc = 4–5.6 K (tunable)**

 

Titanium Nitride (TiN)
----------------------

High Kinetic Inductance Superconductor

 **Role in quantum circuits** 

Kinetic inductance detectors (KIDs), high-impedance resonators, superconducting
            inductors

 **Why it matters** 

TiN has a large kinetic inductance arising from its high normal-state resistivity. This
            makes it ideal for compact high-impedance resonators and microwave kinetic inductance
            detectors (MKIDs). Its Tc is tunable by adjusting nitrogen content during reactive
            sputtering deposition.

 **Key facts** 
* High kinetic inductance — enables compact circuit elements
* Tc tunable via N₂ partial pressure during sputtering deposition
* Hard, chemically stable coating — easy to pattern by etching
* Useful in microwave kinetic inductance detector-style structures
* Relevant for next-generation qubit designs
