Molybdenum (atomic symbol: Mo, atomic number: 42) is a Block D, Group 6, Period 5 element with an atomic weight of . The number of electrons in each of molybdenums shells is [2, 8, 18, 13, 1] and its electron configuration is [Kr] 4d 5 5s 1. The molybdenum atom has a radius of 139 pm and a Van der Waals radius of 209 pm.
Our pure molybdenum and MoCu are the ideal materials as carrier wafers for bonding to LED chips, because of their compatible thermal expansion with semiconductor materials and ceramics, high melting point, high thermal conductivity and electrical conductivity. Molybdenum wafer as heat-sinker for LED chips Made of pure molybdenum or MoCu

High‐performance sensors based on molybdenum disulfide (MoS 2) grown by sulfurization of sputtered molybdenum layers are presented. Using a simple integration scheme, it is found that the electrical conductivity of MoS 2 films is highly sensitive to NH 3 adsorption, consistent with n‐type semiconducting behavior.
The ?rst molybdenum metal application – lead wires in incandescent lamps – appeared in the early days of the 20th century. Molybdenum was chosen for this application because of its stability and strength at elevated temperatures. Since that ?rst application, scientists and engineers have discovered that other properties of molybdenum
