Growing potential uses of gallium oxide (Ga2O3) in high-frequency and high-power devices are creating lucrative avenues for stakeholders. Unlike other semiconductors, gallium oxide can be produced directly from its molten state which further enables large-scale manufacturing of high-quality crystals. Growing awareness about its considerable potential is expected to fuel growth in the gallium oxide market.
Interest in gallium acid has grown significantly over recent years due to its potential as a key option for high breakdown voltage device applications. Gallium oxide can be used in high power switching, owing to its high critical field strength of approximately 8 MV/cm. Gallium oxide also has higher critical electric field strength as compared to silicon, and its higher electron mobility allows a device to have a small size for a specific on-resistance & breakdown voltage. Increasing demand for physically smaller devices is expected to accelerate the demand for Ga2O3, which will further fuel growth in the gallium oxide market.
A recent technoeconomic research conducted by NREL (National Renewable Energy Laboratory) shed light on the potential use of gallium oxide as power electronic technology of the coming time. As per the NREL analysis, gallium oxide wafers could be significantly cheaper to manufacture over silicon carbide. The potential low cost of Ga2O3 wafers over other existing variants is anticipated to fuel growth in the gallium oxide market in the forthcoming years.
Gallium Oxide Market: Introduction
Gallium oxide is an inorganic chemical compound in which Gallium and Oxygen are in a stoichiometric ratio of 2:3. The molecular formula of Gallium Oxide is Ga2O3 and its molecular weight is 187.44 g/mol. Gallium oxide, also known as gallium sesquioxide, is insoluble in water but slightly soluble in alkalis and is a thermally stable compound. Gallium oxide has a large band gap of around 4.8 eV. Larger band gap permits producers to use a thinner device for a certain voltage. In the electronics industry, the more thinner a device, the lower will be the resistance offered by it and thus, it will be more efficient.
The electronic components used in inverters, power supplies and electric motors are expected to be economic, efficient and must also be able to handle high voltage from source. Considering such requirements, gallium oxide is anticipated to be the best available alternative in the semiconductors and electronics market. However, gallium oxide, even though efficient, is not as inexpensive as silicon. However, with technological advancements, the cost of gallium oxide is expected to drop down. This will ensure that the gallium oxide market witnesses growth in near future.
Gallium Oxide Market: Dynamics
For a long time now, silicon has been used in large scale production of semiconductors and microelectronics. However, certain limitations have been found with the use of silicon, such as scalability issue for power electronics. The semiconductor technology demands smaller designs and higher density. For microelectronics, the use of power always acts as an obstacle and the manufacturers are keen on reducing power consumption as well as the heat generated. The technologies used today employ silicon and are close to their operating voltage limits required in many applications. Gallium oxide has been found to function well in such applications. Gallium oxide is also a transparent conductive oxide which offers conductivity and transparency over the visual spectrum. As a result of these factors, the gallium oxide market is anticipated to witness robust growth throughout the forecast period. However, the only hitch in the growth of gallium market will be the cost associated with it.
It has been recently observed in academic studies that field effect transistors (FETs) could potentially benefit from gallium oxide critical electric field strength. The doping limits that might destroy other FET materials do not affect gallium oxide and gallium oxide offers a wide range of conductivity. Gallium oxide is being studied widely for its properties and new scope of applications are being developed.
