We offer most economic, massive size (0.5 grams), and highly crystalline scientific grade black phosphorus (BPs) crystals. Black phosphorus is an infrared (IR) semiconductor with a band gap of 0.3 eV

We offer most economic, massive size (1.0 gram), and highly crystalline scientific grade black phosphorus (BPs) crystals [Note: This product is same as our 0.5 grams and 1 gram BPs crystals.

We offer most economic, massive size (1.0 gram), and highly crystalline scientific grade black phosphorus (BPs) crystals. Black phosphorus is an infrared (IR) semiconductor with a band gap of 0.3 eV

This product contains black phosphorus (BPs) mono- and few-layer flakes solution in ethanol. The BPs solution has been developed by ultrasonic treatment of BPs high quality crystals synthesized

Red phosphorene ribbons are new class of anisotropic semiconductors (~1.7 eV band gap). These quasi-1D crystals have been synthesized through high pressure anvil cell method to realize exfoliation

Silicon phosphide (SiP) is a layered semiconductor crystallizing in 2D anisotropic / orthorhombic crystal phase. It has been shown to undergo indirect (bulk) to direct (monolayer) gap transition from
