SnO: First Stable P-Type 2D Semiconductor Discovered (phys.org)
New submitter Namarrgon writes: Transistors made with Ashutosh Tiwari's new semiconducting material could lead to computers and smartphones that are more than 100 times faster than regular devices. While researchers in this field have recently discovered new types of 2D material such as graphene, molybdenun disulfide and borophene, they have been materials that only allow the movement of N-type, or negative, electrons. In order to create an electronic device, however, you need semiconductor material that allows the movement of both negative electrons and positive charges known as "holes." The tin monoxide material discovered by Tiwari and his team at the University of Utah is the first stable P-type 2D semiconductor material ever in existence.
Vacuum tubes work marvelously well with only electrons.
Tin + Oxygen sounds a lot cheaper (and more readily available) than those iridium, molybdenum, etc compounds, too
